Due to extreme temperatures and the dryness of Mars, it’s thought to be impossible for liquid water to form on the planet’s surface, a critical precondition for habitability. The only hope of finding ...

For years, scientists have been intrigued by mysterious dark streaks running down the slopes of Martian cliffs and craters. These marks, called slope streaks and recurring slope lineae (RSLs), have ...

There might be a hidden ocean's worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were carved by rivers, so it was once warm enough for liquid water. How—and ...

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground. When you purchase through links on our site, we may earn an affiliate commission.

Networks of narrow channels lining the surface of Martian dunes, called “gullies,” have puzzled astronomers for decades. Now, as detailed in a new paper published in the journal Geophysical Research ...

Beneath the surface of Mars lie an array of mysterious "blobs" that might hold clues about the earliest days of our solar system. NASA's InSight Lander discovered the dense lumps scattered through the ...

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...
