In a study published on Feb. 2 in Communications: Earth & Environment, an international team of researchers reveals how, in ...

Advances in technology have reopened the debate over terraforming Mars, shifting it from an impossible dream to a long-term scientific and ethical question.

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 ...

Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ocean. Evidence is mounting that a secret lies beneath the dusty red ...

Prevailing theories suggest that Mars was once covered in a major liquid water system of oceans, rivers, and lakes, which presupposes a thick atmosphere that could maintain temperatures at which ...

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice ...

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 ...
