Earth’s neighbor still has secrets that science is trying to figure out, and one of them is potential signs of life.

Mars has captivated scientists and the public alike for centuries. One of the biggest reasons is the planet’s reddish hue, earning the fourth rock from the sun one of its most popular nicknames — the ...

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 ...

With Mars thought to be wet and habitable once, the study is helping provide new insights into how it came to be the bone-dry ...

On Earth, a similar process occurs when wind generates rolling waves and vortices as it sweeps across the surface of water.

Most planetary scientists agree that Mars’ extreme conditions would be uninhabitable to life as we know it. New research, however, suggests that we might be underestimating the hardiness of lichens.

Mars' distinctive red color comes from the mineral ferrihydrite, which only forms in the presence of cool water, a new study claims. Ferrihydrite also forms at a lower temperature than other minerals ...

New research suggests Mars could have enough water under its surface to form a global ocean. On Monday, scientists released their findings, which are based on seismic measurements captured from NASA’s ...

While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet's surface. Through computer modeling, the ...

CAPE CANAVERAL, Fla. (AP) — Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released ...

A study published last year in the journal Science suggested liquid water is present beneath the south polar ice cap of Mars. Now, a new study in the AGU journal Geophysical Research Letters argues ...
