Possible Life on Mars, ‘Black Hole Stars’ and a Global Diabetes Bombshell – Science News Roundup (Sept 15–16, 2025)
NASA Rover Finds Possible Biosignature – Closest Hint Yet of Life on Mars In a sensational development for astrobiology, NASA announced that Perseverance has collected a Mars rock sample that “could preserve evidence of ancient microbial life” nasa.gov. The rover drilled the sample, nicknamed “Sapphire Canyon,” from an ancient riverbed formation rich in clay – exactly the kind of environment that on Earth traps and preserves organic remains nasa.gov nasa.gov.
