Scientists may be one step closer in their hunt for signs of past life on Mars after the Curiosity rover's latest find.

Last year, NASA’s Curiosity rover made a fascinating discovery after boring into a suspected ancient lake bed on Mars: ...

In 2025, scientists reported the discovery of long-chain organic molecules called alkanes in the ancient mudstones of Mars. Now, in a new study, a team led by Alexander Pavlov of NASA's Goddard Space ...

The discovery suggests that parts of Mars may once have supported tropical-like climates, complete with heavy, sustained rainfall.

This isn’t the famous sample reported last September, but another with different signs of past life we’re struggling to ...

NASA's Curiosity rover has detected long-chain organic molecules, alkanes, in an ancient Martian lake bed. Scientists argue these findings are difficult to explain through non-biological processes ...

NASA's Viking missions to Mars may have discovered evidence for life on the Red Planet after all, according to scientists who ...

Mars Discovery Raises Compelling Questions: Life or Chemistry? Results from NASA’s Perseverance rover reveal organic molecules, unusual minerals, and intriguing rock textures inside Jezero Crater’s ...

A mudstone sample from Jezero Crater shows textures and minerals that on Earth often form through microbial activity. Scientists caution that nonbiological processes could also explain the features, ...

Billions of years ago, Mars’ Jezero Crater held a lake fed by rivers that could have carried minerals and maybe even organic matter. On Earth, places like that are teeming with microbial life. NOVA is ...

The findings suggest that calm lake conditions existed earlier than previously thought.
