A potentially hazardous asteroid named Apophis is set to pass closer to Earth than many satellites on April 13, 2029, but NASA assures there is no risk of impact.

A large asteroid, roughly the size of the Eiffel Tower, is expected to make a notably close approach to Earth on April 13, 2029. According to NASA, the asteroid, known as Apophis, will pass approximately 20,000 miles from the Earth’s surface—closer than many satellites currently in orbit.

Apophis is classified as “potentially hazardous” due to its size and proximity to Earth. It is composed of leftover “raw material” that never coalesced into a planet or moon. When Apophis was first discovered in 2004, there were concerns it might impact Earth in 2029, 2036, or 2068. However, NASA has since monitored the asteroid closely using optical telescopes and ground-based radar, which has allowed scientists to refine its orbital path. Based on this extensive data, NASA is now confident that there is no risk of Apophis impacting Earth for at least the next century.

Apophis was initially discovered on June 19, 2004, by astronomers Roy Tucker, David Tholen, and Fabrizio Bernardi at the Kitt Peak National Observatory near Tucson, Arizona. Due to technical issues and weather conditions, they were only able to observe the asteroid for two days. Later, in December 2004, another team of astronomers in Australia successfully tracked Apophis.

As the 2029 close approach approaches, observatories worldwide, including those in space, will observe Apophis to gain insights into its physical properties. In preparation for this event, NASA has redirected a spacecraft to rendezvous with Apophis shortly after its close approach to Earth. Following its successful mission to collect a sample from the asteroid Bennu, which was returned to Earth in September 2023, NASA’s OSIRIS-REx spacecraft has been renamed OSIRIS-APophis EXplorer (OSIRIS-APEX) and is now en route to study Apophis.

The European Space Agency (ESA) is also planning to send a spacecraft to investigate the asteroid. Apophis is expected to be visible to observers in the Eastern Hemisphere, weather permitting, and can be seen without the aid of a telescope or binoculars.

NASA emphasizes the significance of this event, noting that as Apophis passes close to Earth, it will experience gravitational forces that will pull, twist, stretch, and squeeze the asteroid. This close encounter will alter Apophis’s orbit around the Sun, resulting in a slightly larger orbit and a longer orbital period.

As scientists prepare for this historic event, they are eager to learn more about Apophis and its characteristics, which could provide valuable information about the early solar system and the formation of celestial bodies.

According to NASA, the upcoming close approach of Apophis presents a unique opportunity for research and observation.

Recent findings from NASA’s Chandra telescope suggest that the Milky Way’s spiral arms may extend further into space than previously understood, based on precise measurements of dust clouds.

Using data from powerful X-ray telescopes orbiting Earth, astronomers have made significant strides in measuring the spiral arms of the Milky Way galaxy. A team of researchers has discovered that these arms may stretch farther into space than previously known.

The study utilized data from NASA’s Chandra X-ray Observatory, the most powerful X-ray telescope ever built, and the European Space Agency’s XMM-Newton. By analyzing rare and powerful gamma-ray bursts from distant galaxies, the team was able to measure the distances to dust clouds within the Milky Way’s spiral arms with remarkable accuracy.

As X-rays from these gamma-ray bursts traveled through the Milky Way, some of the light interacted with dust clouds, producing measurable rings. This method allowed for a more direct measurement of distances, relying solely on geometric principles.

“This is a very direct way — relying only on geometry — to precisely measure distances to the Milky Way’s spiral arms,” said Beatrice Vaia, the Italian Ph.D. student who led the study. “Most other methods rely on assumptions about how the Milky Way rotates, which become increasingly uncertain in the outer regions of our galaxy.”

According to the data collected, the dust cloud in the most distant arm of the Milky Way is estimated to be about 3,500 light-years wide. While astronomers have been aware of the Milky Way’s spiral arms for over a century, mapping them has always posed challenges due to Earth’s position within one of those arms.

The breakthrough achieved through the study of gamma-ray bursts, a method unaffected by Earth’s location, could significantly alter our understanding of the Milky Way’s structure and our place within the universe.

“The differences are small, but any revision of these distances is important because they are so fundamental for understanding our galaxy,” stated Ilaria Fornasiero, a Ph.D. student and co-author of the study. “For example, this could mean that astronomers have to revise estimates of the mass of the galaxy because that affects how wide the arms stretch.”

However, the technique does have its limitations. Suitable gamma-ray bursts are rare, with researchers identifying only a handful over the past 25 years that were bright enough and positioned favorably to facilitate measurements of the Milky Way’s spiral arms.

“We will continue to be on the lookout for more,” said co-author Andrea Tiengo, emphasizing the ongoing quest for additional data to refine our understanding of the galaxy.

These findings not only enhance our knowledge of the Milky Way but also underscore the importance of innovative techniques in astronomical research. As scientists continue to explore the universe, the implications of this research may lead to further revelations about the structure and dynamics of our galaxy.

According to NASA, this research represents a significant advancement in our understanding of the Milky Way and highlights the potential for future discoveries using similar methodologies.

NASA has announced three new Moon missions aimed at establishing a permanent human presence on the lunar surface by the end of 2026.

NASA has unveiled three new Moon missions as part of its ambitious Moon Base program, which seeks to create a lasting American presence on the lunar surface by 2026. The announcement was made during a news conference on Tuesday, where NASA Administrator Jared Isaacman emphasized the agency’s swift progress toward what officials are calling “Moon Base.” This long-term lunar outpost is designed to support sustained astronaut missions and facilitate future exploration of Mars.

“America is returning to the Moon,” Isaacman stated, “and this time to stay.” The newly announced missions are intended to assist NASA in testing commercial landers, autonomous vehicles, and various lunar surface operations before astronauts begin spending extended periods on the Moon as part of the Artemis program.

The first mission, Moon Base I, will utilize Blue Origin’s Blue Moon Mark 1 Endurance lander to deliver NASA science payloads to the Shackleton Connecting Ridge, located near the lunar south pole. This region is considered critical due to its potential reserves of water ice. The launch for Moon Base I is targeted for no earlier than fall 2026.

Moon Base II aims to send Astrobotic’s Griffin lander to the lunar surface, carrying over 500 kilograms of cargo, including Astrolab’s FLEX rover. NASA anticipates that the FLEX rover will aid in developing future astronaut mobility systems and enhance autonomous operations on the Moon.

In addition, Moon Base III will transport NASA’s Lunar Vertex science mission, which is designed to study enigmatic lunar swirls—bright formations that scientists believe may be connected to magnetic fields beneath the lunar surface. This mission will also include payloads from the European Space Agency and the Korean Space Agency. Both Moon Base II and Moon Base III are expected to launch before the end of 2026.

NASA officials indicated that these three missions are just the beginning, with more than a dozen additional Moon Base missions anticipated to be announced this year as the agency works toward establishing a sustained lunar presence.

Carlos Garcia-Galan, NASA’s Moon Base program manager, noted that the first phase of this initiative includes 25 launches, 21 lunar landings, and the delivery of approximately four metric tons of cargo to the Moon. Furthermore, NASA has announced new lunar terrain vehicle awards for Astrolab and Lunar Outpost, along with the development of “Moonfall” drones. These drones are designed to scout landing zones, map the lunar surface, and search for subsurface water ice near the south pole.

Isaacman highlighted that NASA is intentionally adopting an iterative approach reminiscent of the agency’s Apollo-era strategy. This method involves repeated missions and commercial partnerships to rapidly test technologies before attempting permanent habitation on the Moon. “We are leveraging the NASA playbook from the 1960s,” Isaacman explained. “Figuring out what works and what doesn’t.”

Despite the excitement surrounding these missions, NASA officials acknowledged that the Moon remains an extremely hostile environment. Challenges such as extreme temperatures, radiation exposure, and constant micrometeorite impacts make repeated robotic missions essential before astronauts can establish a sustained presence on the lunar surface.

“We are really just getting started,” Isaacman concluded, underscoring the agency’s commitment to advancing lunar exploration.

According to Fox News, these missions mark a significant step in NASA’s efforts to return to the Moon and lay the groundwork for future exploration beyond our planet.

Nasa has shut down Voyager 1’s charged particles instrument to conserve power as the spacecraft continues its journey through interstellar space, now over 15 billion miles from Earth.

Nasa has taken the significant step of shutting down one of Voyager 1’s science instruments in a bid to conserve dwindling power. This decision comes as the nearly 49-year-old spacecraft continues its remarkable journey through interstellar space, now more than 15 billion miles from Earth.

Engineers at Nasa’s Jet Propulsion Laboratory (JPL) in Southern California sent commands on Friday to deactivate Voyager 1’s Low-Energy Charged Particles (LECP) experiment. This instrument has operated almost continuously since the spacecraft was launched in 1977. The shutdown is part of ongoing efforts to manage the spacecraft’s power supply, which is diminishing at a rate of approximately 4 watts per year.

“While shutting down a science instrument is not anybody’s preference, it is the best option available,” said Kareem Badaruddin, Voyager mission manager at JPL, in a statement. He noted that Voyager 1 still has two functioning science instruments: one that listens to plasma waves and another that measures magnetic fields. Both instruments continue to send back valuable data from a region of space that no other human-made craft has ever explored.

The decision to shut down the LECP highlights the increasingly delicate balancing act faced by the Voyager team as both spacecraft age far beyond their original mission timelines. Voyager 1 and its twin, Voyager 2, are powered by radioisotope thermoelectric generators that convert heat from decaying plutonium into electricity. After nearly five decades in space, engineers have had to progressively power down heaters and instruments while ensuring that the spacecraft do not become too cold, which could jeopardize key systems, including fuel lines.

“The team remains focused on keeping both Voyagers going for as long as possible,” Badaruddin added.

The urgency of this action was amplified after Voyager 1 experienced an unexpected drop in power during a routine roll maneuver on February 27, according to Nasa. Engineers were concerned that any further decline could trigger the spacecraft’s undervoltage fault protection system, designed to automatically shut down components to safeguard the probe. Recovering from such a fault can be a lengthy process and carries additional risks, prompting the team to act proactively.

The two Voyager probes remain the only spacecraft positioned far enough from Earth to collect data on detecting pressure fronts and regions of varying particle density in the space beyond our heliosphere, according to Nasa.

In a press release, Nasa stated, “Engineers are confident that shutting down the LECP will give Voyager 1 about a year of breathing room.” During this time, they are finalizing a more ambitious energy-saving initiative for both Voyagers, referred to as “the Big Bang.” This plan aims to extend the operational lifespan of the spacecraft further.

The concept behind “the Big Bang” involves swapping out a group of powered devices all at once, hence the nickname. This strategy will involve turning off certain systems and replacing them with lower-power alternatives to ensure the spacecraft remains warm enough to continue gathering scientific data.

The decision to deactivate the LECP was not made hastily. Nasa indicated that mission science and engineering teams had long ago agreed on the order in which spacecraft systems would be shut down as power availability declined. Of the ten original instrument sets carried by the twin probes, seven have now been switched off. Voyager 2’s LECP instrument was deactivated in March 2025.

Given that Voyager 1 is now over 15 billion miles from Earth, commands sent to the spacecraft take approximately 23 hours to arrive. The shutdown sequence itself takes more than three hours to complete. However, one component of the LECP system—a small motor that rotates the sensor to scan in all directions—will remain powered, as it consumes only about half a watt. Engineers hope this will leave the door open for the possibility of restarting the instrument in the future if additional power becomes available.

As the Voyager missions continue to push the boundaries of human exploration, the dedicated team at Nasa remains committed to maximizing the lifespan and scientific output of these extraordinary spacecraft, which have provided invaluable insights into our solar system and beyond.

According to Nasa, the ongoing efforts to manage power consumption are crucial for the continued operation of Voyager 1 and its twin.

The potential discovery of a new dwarf planet, 2017OF201, challenges existing theories about the Kuiper Belt and adds intrigue to the search for the elusive Planet Nine.

A team of scientists at the Institute for Advanced Study School of Natural Sciences in Princeton, New Jersey, has potentially identified a new dwarf planet, which could provide further evidence for the existence of a theoretical super-planet. The researchers announced their findings in a recent news release, revealing the discovery of a trans-Neptune Object (TNO) designated 2017OF201, located beyond the icy expanse of the Kuiper Belt.

TNOs are minor planets that orbit the sun at distances greater than that of Neptune. While many TNOs exist within our solar system, 2017OF201 stands out due to its significant size and unusual orbit. The discovery was made by a team led by Sihao Cheng, along with Jiaxuan Li and Eritas Yang from Princeton University, who utilized advanced computational methods to track the object’s unique trajectory in the sky.

“The object’s aphelion—the farthest point in its orbit from the Sun—is more than 1,600 times that of Earth’s orbit,” Cheng stated in the release. “Meanwhile, its perihelion—the closest point in its orbit to the Sun—is 44.5 times that of Earth’s orbit, which is similar to Pluto’s orbit.” The team estimates that 2017OF201 takes approximately 25,000 years to complete one orbit around the Sun. Yang suggested that this long orbital period indicates the object may have had close encounters with a giant planet, which could have caused it to be ejected into its current wide orbit.

Cheng further elaborated on the object’s potential migration history, proposing that it might have initially been ejected into the Oort Cloud, the most distant region of our solar system, which is known for housing many comets, before being sent back toward the inner solar system.

This discovery has significant implications for our understanding of the outer solar system’s structure. In January 2016, astronomers Konstantin Batygin and Mike Brown from the California Institute of Technology (Caltech) presented research suggesting the existence of a planet approximately 1.5 times the size of Earth in the outer solar system. However, the existence of this so-called Planet Nine remains purely theoretical, as neither Batygin nor Brown has directly observed such a planet.

The theory posits that Planet Nine could be similar in size to Neptune and located far beyond Pluto, within the Kuiper Belt region where 2017OF201 was found. If it exists, Planet Nine is theorized to possess a mass up to ten times that of Earth and to orbit the Sun at a distance up to 30 times greater than that of Neptune. The estimated orbital period for this hypothetical planet ranges from 10,000 to 20,000 Earth years.

Previously, the area beyond the Kuiper Belt was thought to be largely empty, but the discovery of 2017OF201 suggests that this region may be more populated than previously believed. Cheng noted that only about 1% of the object’s orbit is currently visible to astronomers.

“Even though advances in telescopes have enabled us to explore distant parts of the universe, there is still a great deal to discover about our own solar system,” Cheng remarked.

Nasa has indicated that if Planet Nine does exist, it could help explain the peculiar orbits of some smaller objects in the distant Kuiper Belt. As of now, the existence of Planet Nine remains largely theoretical, with its potential presence inferred from gravitational patterns observed in the outer solar system.

This ongoing research highlights the complexities of our solar system and the mysteries that still await discovery, as scientists continue to explore the far reaches of space.

According to NASA, the findings surrounding 2017OF201 could reshape our understanding of the solar system’s architecture and the potential for undiscovered celestial bodies lurking in its depths.

A new study links the M87 black hole to its powerful cosmic jet, revealing how it launches particles at nearly the speed of light.

A groundbreaking study has established a connection between the M87 black hole—the first black hole ever imaged—and its impressive cosmic jet. This research highlights how the black hole propels particles at speeds approaching that of light.

Utilizing significantly enhanced coverage from the global Event Horizon Telescope (EHT), scientists have traced a 3,000-light-year-long cosmic jet back to its likely source. The findings, published in the journal Astronomy & Astrophysics this week, provide crucial insights into the origins and mechanics of the vast cosmic jets emitted by black holes.

M87 is a supermassive black hole located in the Messier 87 galaxy, approximately 55 million light-years from Earth. With a mass 6.5 billion times that of the sun, M87 has garnered attention since the release of its first image in 2019, which was captured using data collected by the EHT in 2017.

Dr. Padi Boyd of NASA emphasized the significance of M87’s activity in a video discussing the black hole’s discovery. “Not only is the black hole supermassive, it’s also active,” she noted. “Just a few percent are active at any given time. Are they turning on and then turning off? That’s an idea… We know there are very high magnetic fields that launch a jet. This image is observational evidence that what we’ve been seeing for a while is actually being launched by a jet connected to that supermassive black hole at the center of M87.”

The M87 black hole not only consumes surrounding gas and dust but also emits powerful jets of charged particles from its poles, forming the extensive jet stream. This duality of behavior has been documented by various scientific outlets, including Scientific American and Space.com.

Saurabh, the team leader at the Max Planck Institute for Radio Astronomy, described the study as an important step toward bridging theoretical concepts about jet launching with direct observational evidence. “Identifying where the jet may originate and how it connects to the black hole’s shadow adds a key piece to the puzzle and points toward a better understanding of how the central engine operates,” he stated.

The Event Horizon Telescope is a collaborative network of eight radio observatories that work together to detect radio waves from astronomical objects, such as galaxies and black holes. This network effectively creates an Earth-sized telescope, allowing for unprecedented observations of these distant phenomena. The term “Event Horizon” refers to the boundary surrounding a black hole beyond which light cannot escape, as defined by the National Science Foundation.

The study’s findings stem from data collected by the Event Horizon Telescope in 2021. However, the authors caution that while the results are robust under the assumptions and tests performed, definitive confirmation and more precise constraints will require future EHT observations. These future observations will necessitate higher sensitivity, improved intermediate-baseline coverage through additional stations, and an expanded frequency range.

As researchers continue to unravel the mysteries of black holes and their jets, this study marks a significant advancement in our understanding of these enigmatic cosmic entities, paving the way for future discoveries in the field of astrophysics, according to Space.com.

The Artemis II crew experienced a historic 40-minute communication blackout as their spacecraft passed behind the Moon’s far side, marking a significant milestone in deep space exploration.

The Artemis II crew officially entered a momentous communications blackout on Monday evening as their spacecraft slipped behind the Moon’s far side, setting new distance records in the process.

NASA reported that the signal loss began at approximately 6:44 p.m. ET and is expected to last around 40 minutes. During this unprecedented event, astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen became the most isolated humans in deep space history.

The blackout occurred as the spacecraft lost line of sight to Earth, with the Moon obstructing satellite communications entirely. Contact is anticipated to resume around 7:25 p.m. ET, when Earth reemerges on the other side of the Moon’s horizon in a moment referred to as “Earthrise.”

Ground control has assured that NASA does not foresee any specific dangers during this mission, but they are prepared for potential contingencies. The astronauts recently practiced essential tasks, such as consuming protein shakes and administering medication, while wearing their bulky orange launch and entry suits. This preparation is crucial in case they need to remain in their gear for an extended period.

In the event of a puncture in the spacecraft, NASA has equipped the Orion module to continuously pump oxygen, ensuring that cabin pressure is maintained. This feature provides the crew with ample time to safely don their pressurized suits.

During the blackout, the Artemis II crew will achieve several significant milestones, including becoming the first humans to witness previously unseen views of the Moon’s far side. At approximately 7:05 p.m. ET, the spacecraft is expected to reach its farthest point from Earth at 252,760 miles, surpassing the Apollo 13 record by about 4,105 miles.

At their closest approach, the Moon will appear roughly the size of a basketball held at arm’s length, according to NASA. Although ground control and the science evaluation room will be unable to communicate with the astronauts during this time, the crew will continue to execute their lunar targeting plan and conduct scientific observations.

The astronauts are set to track historic Apollo sites, scout potential future landing zones, and capture rare views of nearby planets, including Mercury, Venus, Mars, and Saturn. They will also have the unique opportunity to observe a solar eclipse from Orion’s vantage point.

Earlier in the afternoon, the crew broke the distance record set by Apollo 13 in 1970, marking a significant achievement in the ongoing Artemis program.

According to NASA, this mission not only pushes the boundaries of human exploration but also lays the groundwork for future lunar missions and potential manned missions to Mars.

A potentially hazardous asteroid named Apophis is set to pass closer to Earth than many satellites on April 13, 2029, but NASA assures there is no risk of impact.

A large asteroid, roughly the size of the Eiffel Tower, is expected to make a close approach to Earth on April 13, 2029. NASA has confirmed that there is no risk of impact from the asteroid, known as Apophis.

During its flyby, Apophis will come within approximately 20,000 miles of Earth’s surface, a distance closer than many satellites currently in orbit. This classification as a “potentially hazardous” asteroid stems from its size and proximity to our planet.

Apophis was first discovered on June 19, 2004, by astronomers Roy Tucker, David Tholen, and Fabrizio Bernardi at the Kitt Peak National Observatory near Tucson, Arizona. Initial observations were limited to just two days due to technical difficulties and weather conditions. However, in December 2004, a team of Australian astronomers managed to observe the asteroid, allowing for further study.

When Apophis was first detected, there were concerns it might impact Earth in 2029, 2036, or 2068. Since then, astronomers have closely monitored its trajectory using optical telescopes and ground-based radar. NASA has since gained a clearer understanding of Apophis’s orbit and is now confident that there is no risk of collision with Earth for at least the next century.

In preparation for the asteroid’s historic close approach, observatories worldwide, as well as those in space, will observe Apophis to gain insights into its physical properties. NASA has redirected a spacecraft to rendezvous with Apophis shortly after its close encounter with Earth. The spacecraft, originally named OSIRIS-REx, successfully completed its mission to collect a sample from asteroid Bennu and returned it to Earth in September 2023. It has since been renamed OSIRIS-APophis EXplorer (OSIRIS-APEX) and is en route to study Apophis.

The European Space Agency (ESA) is also planning to send a spacecraft to investigate the asteroid. Observers in the Eastern Hemisphere will have the opportunity to view Apophis during its close approach, weather permitting, without the need for telescopes or binoculars.

NASA emphasizes the significance of this event, noting that as Apophis passes by Earth, it will experience gravitational forces that will pull, twist, stretch, and squeeze the asteroid. This close encounter will alter Apophis’s orbit around the Sun, slightly increasing its orbital period.

According to NASA, the close approach of Apophis presents a unique opportunity for scientists to study the asteroid and gain a better understanding of its characteristics and behavior.

This event marks an important milestone in planetary defense and asteroid research, showcasing the advancements in our ability to monitor and understand potentially hazardous objects in our solar system.

Harvard physicist Dr. Avi Loeb suggests that the interstellar object 3I/ATLAS may be a technological probe, given its unusual characteristics and trajectory as it passes through our solar system.

A recently discovered interstellar object, designated 3I/ATLAS, is raising eyebrows among astronomers and scientists alike. Harvard physicist Dr. Avi Loeb has proposed that the object’s peculiar features might indicate it is more than just a typical comet.

“Maybe the trajectory was designed,” Dr. Loeb explained to Fox News Digital. “If it had an objective to sort of be on a reconnaissance mission, to either send mini probes to those planets or monitor them… It seems quite anomalous.”

3I/ATLAS was first detected in early July by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile. This discovery marks only the third time an interstellar object has been observed entering our solar system, according to NASA.

While NASA has classified 3I/ATLAS as a comet, Dr. Loeb pointed out an intriguing detail: an image of the object shows an unexpected glow in front of it, rather than the typical tail that comets exhibit. “Usually with comets, you have a tail, a cometary tail, where dust and gas are shining, reflecting sunlight, and that’s the signature of a comet,” he noted. “Here, you see a glow in front of it, not behind it.”

Measuring approximately 20 kilometers across, 3I/ATLAS is larger than Manhattan and is unusually bright given its distance from Earth. However, Dr. Loeb emphasizes that its most striking feature is its trajectory.

“If you imagine objects entering the solar system from random directions, just one in 500 of them would be aligned so well with the orbits of the planets,” he stated. The object, which originates from the center of the Milky Way galaxy, is also expected to pass near Mars, Venus, and Jupiter—an occurrence that is statistically improbable, according to Loeb.

<p”It also comes close to each of them, with a probability of one in 20,000,” he added.

NASA has indicated that 3I/ATLAS will reach its closest point to the sun—approximately 130 million miles away—on October 30. Dr. Loeb believes that if the object is indeed technological in nature, it could have significant implications for humanity’s future. “If it turns out to be technological, it would obviously have a big impact on the future of humanity,” he remarked. “We have to decide how to respond to that.”

In January, a separate incident involving a Tesla Roadster launched into orbit by SpaceX CEO Elon Musk led to confusion among astronomers, who mistook it for an asteroid. This highlights the complexities and challenges that come with identifying and understanding objects in our solar system.

A spokesperson for NASA did not immediately respond to requests for comment regarding 3I/ATLAS.

As the scientific community continues to study this enigmatic interstellar visitor, the possibility that it may be a technological probe adds a layer of intrigue to the ongoing exploration of our universe, prompting questions about the existence of life beyond Earth and our place in the cosmos.

According to Fox News Digital, Dr. Loeb’s insights underscore the need for further investigation into the nature of 3I/ATLAS and its potential implications for humanity.

Soviet-era spacecraft Kosmos 482 reentered Earth’s atmosphere on Saturday after 53 years in orbit, following a failed attempt to launch toward Venus.

A Soviet spacecraft, known as Kosmos 482, made its uncontrolled reentry into Earth’s atmosphere on Saturday morning, marking the end of a 53-year journey that began with a failed mission to Venus.

The European Union Space Surveillance and Tracking confirmed the spacecraft’s reentry, noting that it had not been detected in subsequent orbits. The European Space Agency’s space debris office also reported the spacecraft’s reentry after it failed to appear on radar at a German monitoring station.

Details regarding the exact location of the spacecraft’s descent and whether any remnants survived the fiery reentry remain unclear. Experts had indicated prior to the event that some parts of the spacecraft, if not all, could potentially survive the descent, given its construction designed to withstand the extreme conditions of Venus, the hottest planet in the solar system.

Scientists assured the public that the likelihood of anyone being struck by debris from the spacecraft was exceedingly low.

Kosmos 482 was launched in 1972 by the Soviet Union as part of a series of missions aimed at exploring Venus. However, this particular mission was thwarted by a rocket malfunction, leaving the spacecraft stranded in Earth’s orbit.

Most of the spacecraft had already fallen back to Earth within a decade of its failed launch, but the spherical lander—estimated to be about 3 feet (1 meter) in diameter—was the last component to succumb to gravity’s pull. Encased in titanium, the lander weighed more than 1,000 pounds (495 kilograms).

As scientists and military experts tracked the spacecraft’s downward trajectory, they encountered challenges in predicting the exact timing and location of its reentry. Solar activity and the spacecraft’s deteriorating condition after decades in space contributed to the uncertainty surrounding its descent.

As of Saturday morning, the U.S. Space Command had not yet confirmed the spacecraft’s reentry, as it continued to collect and analyze data from orbit. The U.S. Space Command routinely monitors dozens of reentries each month, but Kosmos 482 garnered additional attention from both government and private space trackers due to its potential to survive the reentry process.

Unlike many other reentering objects, Kosmos 482 was coming in uncontrolled, without any intervention from flight controllers, who typically aim to direct old satellites and space debris toward vast expanses of water, such as the Pacific Ocean.

According to Fox News, the event marks a significant moment in the history of space exploration, highlighting the long-lasting legacy of Soviet space missions and the ongoing challenges of tracking and managing space debris.

A recent study has linked the M87 black hole to its 3,000-light-year-long jet stream, enhancing our understanding of how black holes launch particles at near-light speed.

A new study has established a connection between the famous M87 black hole—the first black hole ever imaged—and its powerful cosmic jet. This research reveals how the black hole launches particles at nearly the speed of light.

Scientists have traced a 3,000-light-year-long cosmic jet streaming from M87 to its likely source point, thanks to “significantly enhanced coverage” provided by the global Event Horizon Telescope. The findings, published in the journal Astronomy & Astrophysics this week, could help clarify the origins and mechanisms behind the vast cosmic jets emitted by black holes.

M87 is a supermassive black hole located in the Messier 87 galaxy, approximately 55 million light-years from Earth. It is estimated to be 6.5 billion times the mass of the Sun. The first image of M87 was released to the public in 2019, following data collection by the Event Horizon Telescope in 2017.

Dr. Padi Boyd of NASA highlighted the significance of M87, noting its active nature. “Just a few percent are active at any given time. Are they turning on and then turning off? That’s an idea,” she explained in a video about the black hole. Boyd emphasized the presence of very high magnetic fields necessary for jet formation, stating, “This image is observational evidence that what we’ve been seeing for a while is actually being launched by a jet connected to that supermassive black hole at the center of M87.”

M87 not only consumes surrounding gas and dust but also emits powerful jets of charged particles from its poles, forming the extensive jet stream. This dual activity has been discussed in various scientific publications, including Scientific American and Space.com.

“This study represents an early step toward connecting theoretical ideas about jet launching with direct observations,” said Saurabh, the team leader at the Max Planck Institute for Radio Astronomy. He added, “Identifying where the jet may originate and how it connects to the black hole’s shadow adds a key piece to the puzzle and points toward a better understanding of how the central engine operates.”

The Event Horizon Telescope is a global network of eight radio observatories that work together to detect radio waves from astronomical objects, including galaxies and black holes. This collaboration effectively creates an Earth-sized telescope, allowing for unprecedented observations of these distant phenomena. The term “Event Horizon” refers to the boundary surrounding a black hole beyond which light cannot escape, as defined by the National Science Foundation.

The findings were derived from data collected by the Event Horizon Telescope in 2021. However, the authors of the study noted that while the results are robust under the assumptions and tests performed, definitive confirmation and more precise constraints will require future observations with higher sensitivity and improved coverage through additional stations and an expanded frequency range.

These advancements in our understanding of black holes and their jets mark a significant step forward in astrophysics, paving the way for future research and discoveries in the field, according to Space.com.

The next phase of NASA’s Artemis program is set to launch soon, following the successful Artemis II mission that captivated audiences worldwide.

NASA is setting its sights on the moon’s south pole as it prepares for the upcoming Artemis III mission, which will focus on critical docking maneuvers in Earth’s orbit. This mission is slated to launch next year, building on the momentum generated by the recent Artemis II flight.

Following the successful splashdown of the Artemis II crew in the Pacific Ocean on Saturday, entry flight director Rick Henfling emphasized the agency’s forward momentum. “The next mission’s right around the corner,” he stated, highlighting the urgency and excitement surrounding the Artemis program.

Artemis III will see astronauts practicing essential docking procedures with a commercial lunar lander while remaining in Earth’s orbit. This step is crucial for ensuring the mission’s success before any astronauts return to the lunar surface.

In the competitive landscape of lunar exploration, companies led by Elon Musk and Jeff Bezos are vying for dominance. Musk’s SpaceX and Bezos’ Blue Origin are both working on their respective landers, Starship and Blue Moon, with the aim of being the first to demonstrate their capabilities. These companies are also in contention to carry Artemis IV astronauts during the program’s first planned moon landing in 2028.

NASA has already positioned key hardware for the upcoming docking test at Kennedy Space Center. Meanwhile, SpaceX is preparing for another Starship test flight, and Blue Origin is advancing toward its own lunar landing demonstration later this year.

The overarching goal of the Artemis program extends beyond individual missions. NASA and its partners are targeting the moon’s south pole, an area believed to contain significant reserves of ice. This ice could potentially provide water and fuel for a future lunar base, a project that is projected to cost between $20 billion and $30 billion.

As anticipation builds, NASA is expected to announce the crew for Artemis III soon. This mission is designed to echo the testing protocols of the Apollo era, aiming to reduce risks before sending astronauts back to the lunar surface for the first time in over 50 years.

According to The Associated Press, the Artemis program represents a significant step forward in human space exploration, with plans that could reshape our understanding of the moon and its resources.

The potential discovery of a new dwarf planet, 2017OF201, may provide further insights into the elusive Planet Nine theory and reshape our understanding of the Kuiper Belt.

A team of scientists from the Institute for Advanced Study School of Natural Sciences in Princeton, New Jersey, has announced the potential discovery of a new dwarf planet, designated 2017OF201. This large trans-Neptune object (TNO) is located beyond the icy expanse of the Kuiper Belt and could offer new evidence supporting the existence of the theoretical Planet Nine.

Trans-Neptune objects are minor planets that orbit the Sun at distances greater than Neptune. While many TNOs have been identified, 2017OF201 stands out due to its significant size and unusual orbit. The discovery was made by a team led by Sihao Cheng, along with Jiaxuan Li and Eritas Yang, utilizing advanced computational methods to analyze the object’s unique trajectory in the sky.

“The object’s aphelion — the farthest point in its orbit from the Sun — is more than 1,600 times that of Earth’s orbit,” Cheng explained in a news release. “Meanwhile, its perihelion — the closest point to the Sun — is 44.5 times that of Earth’s orbit, which is similar to Pluto’s orbit.” The orbital period of 2017OF201 is estimated to be around 25,000 years, leading Yang to suggest that it may have experienced close encounters with a giant planet, which could have caused it to be ejected into its current wide orbit.

Cheng further noted that the object’s migration could involve multiple stages. “It’s possible that this object was first ejected to the Oort Cloud, the most distant region of our solar system, which is home to many comets, and then sent back,” he said.

This discovery has significant implications for our understanding of the outer solar system’s structure. In January 2016, astronomers Konstantin Batygin and Mike Brown from the California Institute of Technology (Caltech) proposed the existence of a planet approximately 1.5 times the size of Earth, located in the outer solar system. However, the existence of this so-called Planet Nine remains theoretical, as neither Batygin nor Brown has directly observed such a planet.

The Planet Nine hypothesis suggests that this planet, if it exists, is roughly the size of Neptune and is situated far beyond Pluto, in the vicinity of the Kuiper Belt where 2017OF201 was discovered. It is theorized to possess a mass up to ten times that of Earth and to orbit the Sun at a distance up to 30 times greater than that of Neptune. Its orbital period could range from 10,000 to 20,000 Earth years.

Previously, the region beyond the Kuiper Belt was thought to be largely empty. However, the discovery of 2017OF201 challenges this notion, indicating that there may be more objects in this distant area of our solar system than previously believed. Cheng remarked that only about 1% of 2017OF201’s orbit is currently visible to astronomers.

“Even though advances in telescopes have enabled us to explore distant parts of the universe, there is still a great deal to discover about our own solar system,” Cheng stated.

Nasa has indicated that if Planet Nine exists, it could help explain the peculiar orbits of some smaller objects within the distant Kuiper Belt. While Planet Nine remains a theoretical construct, the gravitational patterns observed in the outer solar system continue to fuel speculation about the existence of this distant world.

As researchers delve deeper into the mysteries of our solar system, discoveries like that of 2017OF201 may play a crucial role in reshaping our understanding of celestial dynamics and the potential for undiscovered planets.

According to NASA, the implications of such findings could significantly enhance our knowledge of the solar system’s architecture and the forces at play in the vastness of space.

Four astronauts from the Artemis II mission successfully completed a historic journey around the moon, marking humanity’s return to lunar exploration after more than 50 years.

Four astronauts from the Artemis II mission splashed down off the coast of San Diego on Friday evening, concluding a groundbreaking 10-day journey that marked the first manned mission to the moon in over half a century. The crew landed at 5:07 p.m. Pacific Time after launching from the Kennedy Space Center on April 1 and traveling approximately 252,000 miles from Earth, further than any previous crewed mission.

NASA Administrator Jared Isaacman was present on the USS John P. Murtha ahead of the splashdown. He expressed confidence in the recovery team’s ability to assist the astronauts after their historic mission. “I have no doubt that you’re all going to execute this flawlessly as we get these astronauts who will just complete an absolute historic mission, traveling further into space than any humans have gone before,” Isaacman stated.

He emphasized the significance of this mission, noting, “For the first time, we’ve gone into the lunar environment in more than half a century. We are back in the business of sending astronauts to the moon again.” Isaacman also mentioned plans for future lunar exploration, indicating that once Artemis III launches in 2028, NASA intends to establish a permanent moon base.

After their successful mission, the astronauts—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Mission Specialist Jeremy Hansen—were assisted out of the Orion crew module and taken aboard the USS John P. Murtha for medical evaluations.

The Orion spacecraft reentered Earth’s atmosphere at speeds reaching approximately 25,000 mph. It slowed to around 20 mph through an intricate sequence involving 11 parachutes before landing in the ocean about 60 miles off the California coast. During reentry, the exterior of the spacecraft experienced temperatures soaring to 5,000 degrees Fahrenheit.

The last time astronauts visited the moon was during the Apollo 17 mission in December 1972, three years after the historic Apollo 11 mission marked humanity’s first landing on the lunar surface in 1969.

This successful mission not only showcases NASA’s commitment to returning humans to the moon but also sets the stage for future exploration and potential colonization of lunar environments.

According to Fox News, the Artemis II mission represents a significant milestone in space exploration, rekindling interest in lunar travel and paving the way for subsequent missions aimed at deeper space exploration.

Harvard physicist Dr. Avi Loeb suggests that the interstellar object 3I/ATLAS may be an alien probe, based on its unusual characteristics and trajectory as it passes through our solar system.

A recently discovered interstellar object, designated 3I/ATLAS, has sparked intrigue among astronomers and scientists alike. Harvard physicist Dr. Avi Loeb has raised the possibility that this massive object, which is larger than Manhattan, could be more than just a typical comet.

Dr. Loeb, a science professor at Harvard University, expressed his concerns about the object’s peculiar features, suggesting they may indicate a technological origin. “Maybe the trajectory was designed,” he told Fox News Digital. “If it had an objective to sort of be on a reconnaissance mission, to either send mini probes to those planets or monitor them… It seems quite anomalous.”

3I/ATLAS was first detected in early July by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile. This discovery marks only the third time an interstellar object has been observed entering our solar system, according to NASA.

While NASA has classified 3I/ATLAS as a comet, Dr. Loeb pointed out an unusual glow pattern in images of the object. Unlike typical comets, which exhibit a tail of dust and gas trailing behind them, this object displays a glow in front of it. “Here, you see a glow in front of it, not behind it,” he explained.

Measuring approximately 20 kilometers across, 3I/ATLAS is notably bright for its distance from the Sun. However, Dr. Loeb emphasized that its trajectory is perhaps the most striking aspect. He noted that if objects were entering the solar system randomly, only one in 500 would align so precisely with the orbits of the planets.

Additionally, the interstellar object is expected to pass near Mars, Venus, and Jupiter, a scenario that Dr. Loeb describes as highly improbable if it were merely a random occurrence. “It also comes close to each of them, with a probability of one in 20,000,” he stated.

According to NASA, 3I/ATLAS will reach its closest point to the Sun—approximately 130 million miles away—on October 30. Dr. Loeb speculated about the implications of the object being technological in nature. “If it turns out to be technological, it would obviously have a big impact on the future of humanity,” he remarked. “We have to decide how to respond to that.”

In January, astronomers from the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics mistakenly identified a Tesla Roadster launched into orbit by SpaceX CEO Elon Musk as an asteroid, highlighting the complexities of identifying celestial objects.

As the scientific community continues to analyze 3I/ATLAS, the implications of its characteristics and trajectory remain a topic of discussion and speculation. A spokesperson for NASA did not immediately respond to inquiries regarding the object.

According to Fox News Digital, the ongoing investigation into 3I/ATLAS could reshape our understanding of interstellar objects and their potential significance in the cosmos.

Athena lunar lander successfully reached the moon, but mission controllers remain uncertain about its condition and exact landing location.

Mission controllers have confirmed that the Athena lunar lander successfully touched down on the moon earlier today. However, the status of the spacecraft remains unclear, according to reports from the Associated Press.

While the precise location of Athena’s landing is still unknown, initial communications indicate that the lander was able to establish contact with its ground team. The lander, owned by Intuitive Machines, is equipped with an ice drill, a drone, and two rovers, which are intended for various lunar exploration tasks.

Despite receiving apparent acknowledgments from Athena, mission director and co-founder Tim Crain urged his team to “keep working on the problem.” This statement reflects the ongoing uncertainty surrounding the lander’s condition following its arrival on the lunar surface.

NASA and Intuitive Machines concluded their online live stream shortly after the landing and announced plans to hold a news conference later today to provide updates on Athena’s status.

Athena’s landing marks a significant achievement for Intuitive Machines, especially following the previous challenges faced by the company’s Odysseus lander last year, which landed sideways and created additional pressure for this mission. Athena is the second spacecraft to successfully land on the moon this week, following Firefly Aerospace’s Blue Ghost, which made its touchdown on Sunday.

Firefly’s chief engineer, Will Coogan, celebrated the success of Blue Ghost, stating, “You all stuck the landing. We’re on the moon.” This achievement made Firefly Aerospace the first private company to successfully land a spacecraft on the moon without it crashing or tipping over.

The developments surrounding Athena and Blue Ghost highlight the growing involvement of private companies in lunar exploration, marking a new era in space missions.

As the situation unfolds, further updates will be provided, particularly during the upcoming news conference, which aims to clarify the status of the Athena lunar lander, according to Associated Press.

Nasa has shut down Voyager 1’s charged particles instrument to conserve power as the spacecraft continues its journey through interstellar space, now over 15 billion miles from Earth.

NASA has taken the significant step of shutting down one of Voyager 1’s scientific instruments to conserve dwindling power, as the nearly 49-year-old spacecraft continues its remarkable journey through interstellar space, now more than 15 billion miles from Earth.

Engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent commands on Friday to deactivate Voyager 1’s Low-Energy Charged Particles (LECP) experiment. This instrument has been operational almost continuously since the spacecraft’s launch in 1977.

The decision to turn off the LECP comes as the nuclear-powered probe loses approximately 4 watts of power each year. Mission managers are focused on extending the spacecraft’s operational lifespan as much as possible.

“While shutting down a science instrument is not anybody’s preference, it is the best option available,” said Kareem Badaruddin, Voyager mission manager at JPL, in a statement. “Voyager 1 still has two remaining operating science instruments—one that listens to plasma waves and one that measures magnetic fields. They are still working great, sending back data from a region of space no other human-made craft has ever explored.”

This shutdown highlights the increasingly delicate balancing act facing the Voyager team as both Voyager 1 and its twin, Voyager 2, age far beyond their original mission plans. The two spacecraft are powered by radioisotope thermoelectric generators, which convert heat from decaying plutonium into electricity. After nearly five decades in space, engineers have had to gradually power down heaters and instruments while ensuring that the spacecraft do not become too cold, which could jeopardize key systems, including fuel lines.

“The team remains focused on keeping both Voyagers going for as long as possible,” Badaruddin added.

The urgency of the situation increased after Voyager 1 experienced an unexpected drop in power during a routine roll maneuver on February 27, according to NASA. Engineers were concerned that any further decline could trigger the spacecraft’s undervoltage fault protection system, designed to automatically shut down components to protect the probe. Recovering from such a fault can be a lengthy process and carries additional risks, prompting the team to take action before the spacecraft did so autonomously.

The two Voyager probes remain the only spacecraft far enough from Earth to collect data on detecting pressure fronts and regions of varying particle density in the space beyond our heliosphere, according to NASA.

“Engineers are confident that shutting down the LECP will give Voyager 1 about a year of breathing room,” a NASA press release stated. “They are using this time to finalize a more ambitious energy-saving fix for both Voyagers, which is referred to as ‘the Big Bang.’ This plan is designed to further extend the operational capabilities of the Voyagers.”

The concept behind “the Big Bang” involves swapping out a group of powered devices all at once—hence the nickname. This would entail turning off certain systems and replacing them with lower-power alternatives, ensuring the spacecraft remains warm enough to continue gathering scientific data.

The decision to deactivate the LECP was not made hastily. NASA indicated that mission science and engineering teams had previously agreed on the order in which spacecraft systems would be shut down as power availability declined. Out of the 10 original instrument sets carried by the twin probes, seven have now been switched off. Voyager 2’s LECP instrument was deactivated in March 2025.

Given that Voyager 1 is now over 15 billion miles from Earth, commands take approximately 23 hours to reach the spacecraft. The shutdown sequence itself requires more than three hours to complete. However, one component of the LECP system—a small motor that rotates the sensor to scan in all directions—will remain powered, as it consumes only about half a watt. Engineers hope this will leave the door open for the possibility of restarting the instrument in the future if more power becomes available.

According to NASA, the ongoing efforts to manage power consumption and maintain operational capabilities highlight the dedication of the Voyager team to keep these historic spacecraft functioning for as long as possible.
