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 ...

NASA’s Curiosity rover has assembled a string of chemical evidence from ancient Martian rocks that, taken together, builds the strongest circumstantial case yet for conditions that could have ...

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 ...

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, ...

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

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 ...

Recently, NASA announced that the Mars Perseverance rover has found indications that life may have at one time existed on the Red Planet. The announcement did not mark the first time the space agency ...

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