Astronomers have spotted the longest gamma-ray burst ever seen, a cosmic explosion that lasted seven hours — and they ...

Astronomers have sighted the oldest known stellar explosion, dating back to when the universe was less than a billion years ...

NASA has visualized the cataclysm, which is thought to have caused a mysterious eruption of gamma rays captured by telescopes ...

Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

Determining the "loudest recorded sound" depends on how you define sound and on which measurements you choose to include.

Today’s leading AI models can already write and refine their own software. The question is whether that self-improvement can ...

DAHLGREN, Va.  –  Naval Surface Warfare Center Dahlgren Division recently fired high-speed projectiles into timed explosions ...

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 ...

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” ...

A nuclear winter is a theoretical concept, but if the climate scenario expected to follow a large-scale nuclear war, in which smoke and soot from firestorms block sunlight, came to fruition, global ...

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 ...
