A recent scientific discovery has found that Europa, a moon of Jupiter, likely lacks the necessary tectonic activity to support life in its ocean. This finding reduces the chances of discovering life on the moon, as tectonic activity is thought to be essential for providing energy and nutrients to potential ecosystems.
On January 10, 2026, Jupiter will be at its closest point to Earth, making it visible to the east at sunset and appearing brighter and larger in telescopes. This event provides an ideal opportunity for astronomers and stargazers to observe the gas giant and its four large Galilean moons.
L3Harris has announced the sale of a majority stake in its Space Propulsion and Power Systems business to AE Industrial Partners for $845 million, with the new entity, named Rocketdyne, focusing on the RL10 engine and international expansion. The deal is expected to close in the second half of 2026 and will have significant implications for the aerospace industry.
NASA has decided to return four astronauts from the International Space Station (ISS) earlier than planned due to a medical concern affecting one of the Crew-11 astronauts, who is currently in stable condition but requires more comprehensive care. The early return will be conducted using a SpaceX Dragon capsule, with the Artemis 2 mission remaining on schedule for its February launch.
NASA is bringing some crew members aboard the International Space Station (ISS) back to Earth earlier than planned due to medical concerns with one of the astronauts, a decision that may impact the scheduling of upcoming missions. The early return is not expected to interfere with the Artemis 2 mission, the first crewed lunar mission in over 50 years.
The European Space Agency (ESA) will attend the 18th European Space Conference in Brussels, discussing Europe's space ecosystem and showcasing its Strategy 2040. The conference will focus on key aspects such as autonomy, resilience, competitiveness, and security and defence.
A medical situation on the International Space Station has prompted NASA to bring home four of its seven crew members ahead of schedule, with the astronauts set to return on the SpaceX Crew Dragon spacecraft. The early return marks a rare interruption to a mission due to health concerns, highlighting the challenges of space travel and the importance of prioritizing crew safety.
Scientists plan to utilize NASA"s XRISM mission to search for signs of dark matter decay, which could provide insight into the mysterious substance comprising approximately 85% of the universe"s matter. The mission aims to detect X-ray photons emitted during the potential decay process, offering a possible explanation for the elusive nature of dark matter.
A medical issue affecting one of the crew members has prompted NASA to shorten the Crew 11 mission to the International Space Station, with the crew set to return to Earth ahead of schedule. The crew member in question is reportedly stable, although the nature of the medical issue has not been disclosed.
The XRISM spacecraft has revealed that the supermassive black hole at the heart of the Milky Way, Sagittarius A*, has experienced powerful flares over the last 1,000 years, shedding new light on its violent history. This discovery was made possible by measuring X-rays emitted by a molecular cloud near the center of the galaxy.
A medical issue has prompted NASA to return four astronauts to Earth early from the International Space Station, marking the first medical evacuation in the station's history. The astronaut in question is reported to be in stable condition.
The Vera C. Rubin Observatory has discovered the fastest-spinning asteroid on record, completing one rotation every 1.88 minutes, providing new insights into the composition and behavior of asteroids in our solar system. This discovery has significant implications for the field of astronomy and our understanding of the formation and evolution of asteroids.
The northern lights are expected to be visible in 12 states across the northern US on January 8-9 due to an incoming stream of fast solar wind and potential coronal mass ejections. This phenomenon is a result of geomagnetic activity that may reach minor storm levels, providing a rare opportunity for aurora chasers to witness the spectacle.
A philanthropic organization founded by the former CEO of Google has secured private funding for four next-generation telescopes, including a space-based observatory called Lazuli, which will have 70% more collecting area than the Hubble Space Telescope. This development marks a significant milestone in the application of commercial spaceflight lessons to large-aperture astronomy.
On January 8, Comet 24P/Schaumasse made its closest approach to the Sun, passing within 109.7 million miles of our star, an event that, while not visible to the naked eye due to its magnitude of approximately +10.8, provides valuable opportunities for scientific study and insight into the behavior of comets in our solar system. This perihelion passage is part of the comet's highly elliptical orbit, which extends beyond Jupiter's path before curving back towards the Sun.
The European Space Agency (ESA) has announced its key milestones for 2026, including the arrival of the BepiColombo mission at Mercury, the launch of the Smile mission to study Earth's reaction to solar particles, and several Earth Observation and Navigation launches. These milestones mark significant steps forward for the ESA in its ongoing efforts to explore space and improve our understanding of the universe.
Billionaire Eric Schmidt and his wife Wendy have announced a significant investment in private telescope projects, including the Lazuli space telescope, which is expected to launch in late 2028 and begin scientific operations in 2029. This investment aims to push the boundaries of space-based astronomy and potentially pave the way for future breakthroughs in our understanding of the universe.
The space industry is grappling with a complex cybersecurity regulatory challenge due to inconsistent international approaches and unclear long-term global compliance requirements, posing significant risks to the security of space-based assets. This challenge underscores the need for a coordinated and harmonized approach to cybersecurity in the space sector.
A tidal disruption event, known as "the Whippet", has been detected at the Palomar Observatory in California, releasing an enormous amount of energy equivalent to 400 billion suns.
