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.

Volcanoes might seem like nature’s incinerators, but using them to burn up trash would be dangerous and disrespectful to indigenous people who view them as sacred.

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.

A key goal of the Chang'e-5 mission was to find evidence of some of the youngest volcanic eruptions on 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.

Earth's magnetic field locks information into lava as it cools into rock. Millions of years later, scientists can decipher this magnetic data to build geologic timelines and maps.

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

The molten rock that feeds volcanoes can be stored in the Earth’s crust for as long as a thousand years, a result which may help with volcanic hazard management and better forecasting of when eruptions might occur.
