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.

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.

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.

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 ...

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 ...

The surface of Mars is woven with beautiful gullies. Until recently, scientists thought that liquid water played a role in carving out these vein-like channels.

The city witnessed intense waterlogging this year during monsoon, and to prepare the region for the next rainy season, the gullies ar a significant part.
