By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Green dots show the locations of 186 gamma-ray bursts observed by the Large Area Telescope (LAT) on NASA's Fermi satellite during its first decade. Some noteworthy bursts are highlighted and labeled.

Astronomers have witnessed a young, sun-like star blasting out high-energy gamma radiation for the first time. The observation represents the first evidence that this type of low-mass star, called a T ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of "Ask a Spaceman" and "Space Radio," and author of "How to Die in Space." Sutter contributed this article to ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed. Lead ...

The discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation. When you purchase through links on our site, we may earn an ...
