JWST Maps Dark Matter With Unprecedented Detail
Using James Webb Space Telescope observations of the COSMOS field, researchers inferred dark matter’s distribution via gravitational lensing—revealing finer structure and new clumps compared with earlier maps.
Europa: New Evidence of Ammonia Near Surface Fractures
A reanalysis of Galileo spacecraft data found ammonia-bearing compounds on Europa’s surface—especially near fractured regions—hinting that material from a subsurface ocean may have reached the surface.
NASA: La Niña Temporarily Slowed Sea-Level Rise in 2025
A NASA/JPL analysis found global mean sea level rose just 0.08 cm in 2025—likely because La Niña shifted more water onto land via increased rainfall. The long-term trend is still up, but this shows how Earth’s climate cycle can create short-term breathers in t
NASA’s Commercial Satellite Data Acquisition Program Releases Archived and Tasked Multispectral Data from Satellogic
NASA’s Commercial Satellite Data Acquisition (CSDA) program is releasing a trove of archived and on‑demand multispectral imagery from commercial partner Satellogic, giving researchers, NGOs, and farmers free access to high‑resolution Earth observation data.
Mapping Perseverance’s Route With AI
NASA scientists used artificial intelligence to automatically map the Perseverance rover’s traverses on Mars, turning raw HiRISE images into a detailed, searchable route map.
