Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

Research suggests some metals’ semicore electrons may be more active on Earth’s surface than previously thought.

It is now thought that the source of this anomaly was a phase transition in which one mineral’s structure was altered.

Seismic waves created by earthquakes as they travel through the planet's interior change speed and direction as they move through different materials. Things like rock type, density, and temperature ...

Earth's internal structure consists of four layers: the crust, mantle, outer core (liquid iron), and inner core (solid iron), with temperatures increasing significantly with depth, reaching values ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

Two recent studies used seismic data from NASA's retired InSight mission to shed light on what lies beneath Mars’ surface and ...

Extreme chemical reactions could explain why Earth's middle layer has so much carbon. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

Scientists detect a solid inner core on Mars for the first time, revealing a new chapter in planetary evolution.
