When researchers reconstructed lava flows on Mars, they realized the red planet is a lot more active than they previously thought.

Rocks on Mars that date back nearly 4 billion years are composed of large grains of olivine, which tints Hawaiian beaches green back on Earth.

A hidden layer of soil and dust on the moon is much thicker than previously known. It may reveal new info about the history of the moon.

New findings get researchers "one step closer to improving the monitoring of volcanic unrest, which aims to protect lives, infrastructure, and crops."

New research digs into ferrovolcanism, volcanoes on planets made of metal. It could give us a glimpse at what those metallic worlds might look like.

New research clears up a longstanding question about explosive volcanic eruptions like the ones at Mount St. Helens in 1980.

There may be a way for scientists to predict when volcanoes will erupt by closely monitoring pressure changes, researchers say.

A new model helps "assess whether similar lava tubes on the moon or Mars would be capable of hosting a permanent human habitat."

"Understanding basic processes having to do with volcanoes will ultimately help us make better forecasting calls when it comes to eruptions."
