Glaciers Tell A Story Of Ancient Mars
A new paper published in Icarus describes, maps and dates how glaciers and glacial runoff sculpted the northeastern rim of Mars’ Hellas basin over the last 3 billion years. The […]

Lake Eridania On Mars
Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA’s Mars Express. This […]

Understanding The Structure Of Ancient Earth
A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth’s history. These plagioclase-rich igneous rock […]

The Presence Of Liquid Water Is The Most Probable Explanation For Data Collected By Mars Insight
Data about Mars’ planetary crust gathered from the Mars InSight lander are best explained by the conclusion that the crust has stores of liquid water. Analysis led by Vashan Wright, […]

There Are Oceans Of Water On Mars. They’re Just Too Deep To Tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet’s surface.

Looking For Ancient Rock Beyond Earth
Earth’s continents are each different and have changed through time, but they all have one thing in common — the presence of one or more cratons, forming their ancient nuclei. […]
