Ice may be present a few centimeters below the moon's surface in more areas of the lunar polar regions than was previously thought due to large, yet highly localized, variations in surface temperatures. The results, published...
A team of scientists from University College Cork (UCC), the University of Connecticut, and the Natural History Museum of Vienna have uncovered how plants responded to catastrophic climate changes 250 million years ago. Their findings, published in GSA...

Large magma bodies found beneath dormant volcanoes, surprising scientists

New Cornell University led-research challenges the long-standing belief that active volcanoes have large magma bodies that are expelled during eruptions and then dissipate over...

Hawai’i’s two most active volcanoes share a magma source, research reveals

Using a nearly 200-year record of lava chemistry from Kīlauea and Maunaloa, Earth scientists from the University of Hawai'i at Mānoa and colleagues revealed...

Magmatic fluids and melts may lie beneath dormant German volcanoes

Central Europe is typically not on most people's radar when it comes to assessing volcanic risk. However, as recently as 11,000 years ago, volcanoes...

Tiny glass beads suggest the moon had active volcanoes when dinosaurs roamed Earth

Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests. The evidence: three tiny glass beads plucked from the surface of the moon and brought...

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...
