Mars lost habitability due to its own climate self-limiting cycle
Monday, 07 July 2025 11:57
Mars may once have flowed with rivers and lakes, but a new study led by University of Chicago planetary scientist Edwin Kite suggests its warm periods were fleeting and ultimately doomed by a self-regulating climate system. Published July 2 in Nature, the research presents a model in which increasing solar brightness briefly allowed water to flow before triggering a geochemical response that loc NASA shares SPHEREx sky survey data weekly to enable global cosmic research
Monday, 07 July 2025 11:57
NASA's SPHEREx space telescope, launched in March, has begun publicly releasing data from its infrared sky survey, offering scientists worldwide weekly access to its extensive cosmic observations. The mission is designed to map the entire sky twice a year over a two-year period, capturing images in 102 infrared wavelengths to support investigations ranging from the origins of the universe to the NASA spacecraft captures detailed images of Donaldjohanson asteroid

Why is there no life on Mars? Rover finds a clue
Sunday, 06 July 2025 07:38
Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth?
A discovery made by a NASA rover has offered a clue for this mystery, new research said Wednesday, suggesting that while rivers once sporadically flowed on Mars, it was doomed to mostly be a desert planet.

Sunday, 06 July 2025 07:38
Astronomers on Wednesday confirmed the discovery of an interstellar object racing through our Solar System - only the third ever spotted, though scientists suspect many more may slip past unnoticed.
The visitor from the stars, designated 3I/Atlas, is likely the largest yet detected, and has been classified as a comet, or cosmic snowball.
