Mars’s Coloe Fossae reveals a landscape shaped by ancient ice ages, with deep valleys, cratered terrain, and frozen debris flows preserved from a time when the planet’s climate dramatically shifted.

As we travel from Mars’s equator toward the planet’s northern regions, we arrive at Coloe Fossae. This landscape is characterized by long, shallow grooves that cut across an area filled with steep ...

Simulation results show that Mars, despite its similar size to Earth, has a considerable influence on the Milankovitch cycles ...

What can craters on Mars teach scientists about the Red Planet’s climate history? This is what a recent study published in Geology hopes to address as a team of researchers investigated ice buildup ...

For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today. A new study published online on September 2, ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's ...
