Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime. These transient phenomena ...

The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By tracking how these eruptions light up the high‑energy sky, researchers have ...

A record-shattering stellar blast has been caught on camera in unprecedented detail, and the footage is forcing astronomers ...

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

Distinguishing between different types of gamma-ray bursts just got a lot more complicated. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A ...

A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

Dubbed the "brightest of all time," or the BOAT, a gamma-ray burst detected in 2022 continues to astound astronomers, revealing severe effects in Earth's atmosphere. When you purchase through links on ...

For as long as people have watched storms roll across the sky, lightning has inspired awe and fear. You can see the flash and ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to ...

Scientists have announced the discovery of nearly 300 gamma ray pulsars. The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, ...

On Oct. 9, 2022, the orbiting Swift and Fermi gamma-ray detectors observed the brightest gamma-ray burst (GRB) ever seen: GRB 221009A. Astronomers around the world quickly responded by turning as many ...
