'Superdeep' diamond deepens our understanding of plate tectonics

A unique combination of minerals trapped inside a "superdeep" diamond that originated hundreds of kilometers beneath Earth's surface sheds new light on plate tectonics, the geological processes that give rise to mountains, ...

Europa's plate tectonic activity is unlike Earth's

Plate tectonics represents a defining framework of modern geoscience, accounting for large-scale features on Earth's surface, such as mountains and valleys, as well as the processes that shape them, like volcanoes and earthquakes. ...

Magma floods erupt from deeper sources than earlier believed

An international group of geologists has demonstrated with computer simulation that huge magma eruptions can initiate deeper below the Earth's surface than previously believed. Such flood basalt eruptions have caused many ...

NASA's InSight lander detects stunning meteoroid impact on Mars

NASA's InSight lander recorded a magnitude 4 marsquake last Dec. 24, but scientists learned only later the cause of that quake: a meteoroid strike estimated to be one of the biggest seen on Mars since NASA began exploring ...
