Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles ...

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

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The ...

The volcanic ash cloud is made of tiny, sharp particles of rock, minerals and volcanic glass. The formation of the particles ...

The physics of java and lava are actually quite similar, at least when it comes to bubbles, according to a surprising study.

A large formation of granite discovered below the lunar surface likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted early in the Moon's history -- as long as ...

What is the importance of studying explosive volcanism on Venus? This is what a study published in the Journal of Geophysical ...

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 ...

A Canary Islands volcano pushed rivers of molten lava through the earth. Now scientists and explorers trek through the cooling underground, looking for insights into life on this planet—and perhaps on ...
