In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to ...

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

Microscopic evidence reveals how cooling magma chambers were recharged by fresh volcanic injections 2.5 billion years ago to ...

Extinct volcanoes are hard to study – we never see them erupt. Using a unique experimental technique, we were able to recreate a certain type of extinct volcano in a lab, learning more about the magma ...

Volcanic eruptions are dangerous and difficult to predict. A team has found that the ratio of atoms in specific gases released from volcanic fumaroles (gaps in the Earth's surface) can provide an ...

Within the deposits of extinct volcanoes around the world, a mysterious magma may be Earth’s new source for rare metals. This iron-rich magma could be full of the metals that help power some of the ...

Q: Is all volcanic magma the same temperature? A: The temperature of magma inside a volcano — and of lava as it emerges — is highly variable and depends in part on the chemical composition of the ...
