Gullies that lace the surface of Mars look similar to those carved out on Earth by flowing water — but a new study shows that the life-giving liquid likely did not create the Martian features.

The gullies of Mars remain active and tend to form during cold weather, implicating frozen carbon dioxide — also known as "dry ice" — rather than liquid water, researchers said. "As recently ...

Gullies on Mars that appeared to have possibly been carved by water were probably dug out by great chunks of dry ice, a pair of French researchers say. Dry ice, not water, responsible for many ...

Mars' gullies are different than the RSL, but, according to Nunez, some researchers had thought that liquid water might also be the mechanism forming the gullies. However, he noted that the "main ...

Gullies are common on the Martian surface, mostly occurring between 30 and 50 degrees latitude in both the northern and southern hemispheres. On Earth, similar gullies are formed by flowing liquid ...

Mars's gullies may be formed by dry ice processes rather than flowing liquid water, as previously thought. Scientists show that, during late winter and spring, underneath the seasonal CO2 ice ...

But just because the gullies on Mars weren’t formed by liquid water doesn’t mean the Red Planet was always a dry, barren place. Last year, scientists discovered a feature called recurring ...

A study offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars.

A Brown University-led research team explains in a new study how gullies on the slopes of Martian craters could have formed by on-and-off periods of meltwater from ice on and beneath the planet ...

Gullies on the slopes of Martian craters were likely created by the “very recent” flow of water, according to a new study that sheds more light on whether life could exist on the Red Planet ...

Gullies on Mars could have formed by melting of water ice during periods of high obliquity. Science , 2023; 380 (6652): 1363 DOI: 10.1126/science.abk2464 Cite This Page : ...
