It is a scientific consensus that water once flowed on Mars, and that it had a denser atmosphere, meaning that it was once habitable.

The National Aeronautics and Space Administration scientists have been startled by the latest discovery of the space agency’s ...

The NASA Curiosity rover has detected the largest organic molecules found to date on Mars, opening a window into the red planet’s past. The newly detected compounds suggest complex organic chemistry ...

A rock on Mars spilled a surprising yellow treasure after Curiosity accidentally cracked through its unremarkable exterior. When the rover rolled its 899-kilogram (1,982-pound) body over the fragile ...

The Mars Curiosity rover has found the largest organic molecules yet on the Red Planet. Organic molecules are the building blocks of life, although they can also be produced by geological processes.

This graphic shows the long-chain organic molecules decane, undecane, and dodecane. These are the largest organic molecules discovered on Mars to date. NASA/Dan Gallagher Despite its freezing ...

One of NASA's Mars rovers has discovered a strange rock filled with yellow sulfur crystals. The Curiosity rover made the exciting find after accidentally running over a rock on May 30, which cracked ...

Data from NASA's Curiosity rover collected on Mars is shedding new light on how the Red Planet became uninhabitable in the distant past due to a changing climate that caused the surface water to ...

NASA’s Mars Reconnaissance Orbiter (MRO) has captured what’s believed to be the first orbital image of the Curiosity rover “on the move.” The remarkable photograph, enhanced to bring out the details, ...

NASA's Mars Curiosity rover drilled into a rock and found that it contained a clay-like material. That's the news. The implication is much larger: Mars may once have had an environment hospitable to ...

Researchers at NYU Abu Dhabi have uncovered evidence that water once flowed beneath Martian sand dunes — suggesting that the Red Planet may have once had conditions capable of supporting life. Scienti ...
