Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding.

Explore the fascinating magnetic properties of burnt matchsticks in this creative science experiment! Watch how ring and bar ...

In a new study, researchers show that gas bubbles can form in the rising magma not only due to a drop in pressure but also due to shear forces. If these gas bubbles grow in the volcanic vent early on ...

Cradled in the nose of a high-altitude research airplane, a new NASA sensor has taken to the skies to help geoscientists map rocks hosting lithium and other critical minerals on Earth’s surface some ...

The new station—with a continuous real-time data stream from a seismometer, GPS, cameras and infrasound sensors—will provide ...

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The intensity of a volcanic eruption is shaped by how many gas bubbles develop ...

On a quiet Sunday morning in Ethiopia’s Afar region, the ground shook, the sky blackened, and a volcano long considered ...

Scientists have observed cryovolcanoes erupting on comet 3I/ATLAS — giving us a new clue about what's inside it.

A volcano in northern Ethiopia erupted Sunday, marking its first known eruption in 12,000 years. The volcano, called Hayli ...

Hawaii’s Kilauea, one of Earth’s most active volcanoes, sent lava fountains spewing into the air, obliterating a U.S.
