Researchers simulated Martian permafrost and ice cap conditions in a laboratory, exposing *Escherichia coli* samples in pure water ice and water-sediment mixtures to cosmic radiation equivalent to 50 ...

In a groundbreaking discovery, scientists have identified a massive ice deposit on Mars in a region previously thought to be ...

New study shows Mars went through shrinking ice ages, revealing how it lost water and where future missions might find what's left.

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

Massive volcanic eruptions billions of years ago may have made it snow on Mars, leaving thick buried ice near the planet’s equator.

November's Sky Above episode features a supermoon, meteor shower, and interstellar comet, with experts discussing these ...

UNIVERSITY PARK, Pa. — Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the Red Planet. By recreating Mars-like conditions in the lab, ...

We take a look at what the discovery of liquid water under Mars’ surface could mean, we discover how space affects the human body, and Aussie astronomers discover the fastest-growing black hole. (Scie ...

Scientists have long known that Mars holds plenty of ice, but most of it is thought to be near the planet’s poles. So when ...
