A new Astrobiology study suggests non biological processes may not fully explain organic molecules found by NASA’s Curiosity rover on Mars. Could ancient life be a possible answer?

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 ...

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 ...
