Asteroid crater on Earth provides clues about Martian craters

The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on ...

When volcanoes go metal

What would a volcano—and its lava flows—look like on a planetary body made primarily of metal? A pilot study from North Carolina State University offers insights into ferrovolcanism that could help scientists interpret ...

Life on an airless Earth

In hidden pockets around the world, tiny creatures consume toxins and wait for their day to again rule the Earth.

Crystals reveal the danger of sleeping volcanoes

Most active volcanoes on Earth are dormant, meaning that they have not erupted for hundreds or even thousands of years, and are normally not considered hazardous by the local population. A team of volcanologists from the ...

A new way of looking at the Earth's interior

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem ...

Venus' ancient layered, folded rocks point to volcanic origin

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic ...
