Radar images previously revealed thousands of buried glacier-like formations in the planet’s northern and southern hemispheres.

A glacier is, after all, a big chunk of ice and it flows and gets a form that tells us something about how soft it is. We then compared this with how glaciers on Earth behave and from that we have been able to make models for the ice flow,” she said.
