A recent study showed that Mars was warm and wet billions of years ago. The finding contrasts with another theory that this era was mainly cold and icy. The result has implications for the idea that ...

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 ...

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

Mars has long tempted scientists with hints of chemistry that might once have supported life. Now a NASA-led study argues ...

Organic molecules found by the Curiosity rover are too common to be explained by any process we know, other than life, according to a new study. That, of course, doesn’t rule out the possibility that ...

Organic compounds discovered on the Red Planet cannot be fully explained by non-biological sources, say astrobiologists.

A year ago, NASA announced that its Mars rover Curiosity had discovered long-chain organic compounds. Their quantity suggests ...

Scientists studying a rock sample collected by NASA’s Curiosity rover have uncovered something tantalizing: the largest ...
