Glaciers flowed on ancient Mars, but slowly

The weight and grinding movement of glaciers has carved distinctive valleys and fjords into Earth's surface. Because Mars lacks similar landscapes, researchers believed ancient ice masses on the Red Planet must have been ...

Estimating uranium and thorium abundance with geoneutrinos

A planet's interior heat comes from two principal sources: leftover energy amassed from collisions between planetesimals during the accretion of the planet and the subsequent decay of radioactive elements embedded within ...

AI illuminates permanently shadowed regions on the moon

With the help of artificial intelligence, an international research team led by ETH Zurich has explored the moon's permanently shadowed regions. The information they have obtained about the area's surface properties will ...

Understanding how hillslopes connect ecosystems

Hillslopes are essential landscape features. They physically tie ridges to valleys and link terrestrial and aquatic ecosystems through sediment, water, and nutrients. Understanding how hillslopes interact is critical to understanding ...

Deep earthquakes suggest well-hydrated Mariana subduction zone

On the surface, subduction zones manifest as oceanic trenches, the deepest of which is the Mariana Trench in the Pacific Ocean. One notable feature of many trenches is their outer rise, a shallow bulge on the outskirts of ...
