A new study published last week is giving us a better idea. The research builds on previous hypotheses theorizing that Ice Ages occur on a predictable timeline that relates to the geometry of Earth’s ...

Coloe Fossae was shaped by powerful tectonics, which stretched and cracked Mars's crust, causing chunks of ground to collapse ...

Recent high-resolution imaging of Mars has unveiled deep ‘scratches’ and craters that suggest the Red Planet once experienced ...

First, what is an ice age? It’s when the Earth has cold temperatures for a long time – millions to tens of millions of years – that lead to ice sheets and glaciers covering large areas of its surface.

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, ...

A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to predict ...

Traveling up from the Mars equator toward its north pole, we find Coloe Fossae: a set of intriguing scratches within a region ...

In a study published November 6 in the journal Science, researchers used space dust to make a 30,000-year timeline of ice ...
