NASA’s Psyche mission captures a stunning view of Mars’ Huygens crater

NASA’s Psyche mission recently photographed Huygens Crater on Mars, offering a sharp new look at the planet’s ancient surface features. The image adds to the mission’s broader scientific value by demonstrating how spacecraft en route to their primary target can still produce useful observations. Source 1

NASA shares striking Milky Way view from the International Space Station

NASA released a dramatic image of the Milky Way seen from the ISS, where the galaxy appears brighter and wider without Earth’s city lights and atmospheric haze. The photo highlights how space-based observation can reveal details that are difficult to capture from the ground. Source 1

Scientists report a possible dark matter imprint in gravitational waves

Researchers say they may have found a subtle signature that could hint at dark matter’s influence on gravitational-wave signals. The result is still preliminary, and the scientists stress that more observations and analysis are needed before any claim of confirmed dark matter detection can be made. Source 1

NASA’s MAVEN detects a first-of-its-kind atmospheric effect in Mars’ upper air

NASA’s MAVEN spacecraft has detected a newly identified effect deep in Mars’ atmosphere, adding to the mission’s long record of revealing how the Red Planet loses atmosphere over time. The finding could help scientists better understand Mars’ climate history and atmospheric evolution. Source 1

New observations suggest a supermassive black hole may be suppressing star formation

Astronomers reported evidence that the supermassive black hole at a galaxy’s center may be pushing out material in a way that prevents new stars from forming. If confirmed, the result would help explain how black holes can regulate the growth and evolution of galaxies. Source 1

Asteroid 2026 JH2 makes a close flyby of Earth

Asteroid 2026 JH2 is passing near Earth today after being discovered only days earlier by astronomers at the Mount Lemmon Survey in Arizona. While close approaches often attract attention, current reports indicate this object is being monitored as part of ongoing planetary defense tracking. Source 1

A strange ‘inside-out’ planetary system may challenge theories of planet formation

Scientists have identified LHS 1903, a system that appears to contain rocky planets in an unusual order that does not fit standard planet-formation expectations. Researchers think the planets may have formed sequentially rather than all at once, which could force astronomers to rethink how worlds develop around stars. Source 2

Vitamin K study reveals a new bone-regulation pathway

A new study shows that vitamin K-dependent γ-carboxylation in osteoblasts influences bone breakdown through the signaling protein GAS6. In mice, blocking the pathway increased bone mass, suggesting a possible future route for osteoporosis therapies. Source 3

Young adults’ sleep and mental distress patterns mapped in new Danish research

Researchers from the University of Copenhagen have mapped a complex set of factors that may trap young adults in poor sleep patterns and mental distress. The findings are already being used to design interventions for young people in a Danish municipality. Source 3

New vaccine-combination research points to stronger immune protection

Scientists at La Jolla Institute for Immunology reported that combining key vaccine ingredients may give the body better tools to fight infection. The work could help guide future vaccine design by improving immune responses more efficiently. Source 3

A major mass spectrometry database receives a 2026 update

Wiley has released the 2026 edition of the Wiley Registry of Mass Spectral Data, one of the world’s largest reference databases for identifying unknown chemical compounds. The update is important for chemical analysis, forensics, environmental testing, and research laboratories worldwide. Source 3

Clinical trial aims to treat type 2 diabetes by using steam energy on the digestive tract

HonorHealth Research Institute is preparing a clinical trial that would modify the lining of the digestive tract using steam energy to control type 2 diabetes without drugs. If successful, the approach could offer a new non-pharmaceutical treatment option for a major chronic disease. Source 3
