Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently than previously assumed. This indicates the presence of zones of rocks that are colder, or have a...
Montana State University scientists say the frozen remnants of an ancient forest discovered 600 feet above the modern tree line on the Beartooth Plateau may portend possible changes for the alpine ecosystem if the climate continues...

First detection of frost on the solar system’s tallest volcanoes on Mars

For the first time, water frost has been detected on the colossal volcanoes on Mars, which are the largest mountains in the solar system....

Study suggests Io’s volcanoes have been active for 4.5 billion years

A team of geologists and planetary scientists from the California Institute of Technology, the University of California Santa Cruz, New York University, and NASA...

How much of Venus’s atmosphere is coming from volcanoes?

There's a lot we don't know about the planet nearest to us. Venus is shrouded in clouds, making speculation about what's happening on its...

Mercury rising: Study sheds new light on ancient volcanoes’ environmental impact

Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and...

One of California’s riskiest volcanoes is very active. Is an eruption coming?

One of California's riskiest volcanoes has for decades been undergoing geological changes and seismic activity, which are sometimes a precursor to an eruption, but—thankfully—no...

Washington’s volcanoes are experiencing seismic tremors from an unlikely source—glaciers

Most people think of seismic activity as the result of movement along faults or of violent volcanic eruptions. But seismic events can have other...

What would it take to see exoplanet volcanoes?

Even with the clearest image from the best telescope in the world, astronomers still won't know what they're looking at. It takes a fundamental...

Is it life, or is it volcanoes?

Astronomers are working hard to understand biosignatures and how they indicate life's presence on an exoplanet. But each planet we encounter is a unique...

Carbon dioxide, not water, triggers explosive basaltic volcanoes

Geoscientists have long thought that water—along with shallow magma stored in Earth's crust—drives volcanoes to erupt. Now, thanks to newly developed research tools at...

Do volcanoes add more carbon than they take away?

In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a...

Predictive power of climate models may be masked by volcanoes

Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study published in Science Advances. The research, led...

13 volcanoes seen from space

Have you ever wondered what a volcano looks like from space? Today, we're counting down our picks of the most impressive volcanoes around the...
