At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers ...

Great things can come from failure when it comes to geology. The Midcontinent rift formed about 1.1 billion years ago and ...

A new seismic study reveals that Earth’s largest volcanic event fundamentally transformed the oceanic plate beneath the ...

The Earth's outer layer is broken into moving, interacting plates whose motion at the surface generates most earthquakes, creates volcanoes and builds mountains. In this image, the orange layer ...

The Rocky Mountains have always looked like a geological non sequitur, a towering spine of peaks sitting far from the ...

A study of a giant impact crater on Venus suggests that its lithosphere was too thick to have had Earth-like plate tectonics, at least for much of the past billion years. At some point between 300 ...

Mead crater, the largest impact basin on Venus, is encircled by two rocky rings, which provide valuable information about the planet's lithosphere. At some point between 300 million and 1 billion ...
