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 ...

A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are the ...

It's named BOAT because it's "the Brightest Of All Time." It's also the first of its kind to affect our planet's upper ionosphere. When you purchase through links on our site, we may earn an affiliate ...

In early October 2022 a wave of high-energy radiation swept over Earth from a gamma-ray burst, one of the most singularly catastrophic and violent events the cosmos has to offer. Astronomers quickly ...

For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as ‘gamma-ray bursts’ or GRBs.

Stars like the Sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the Sun ...

Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called “Death Star,” which is also famed for looking like a ...

Amy Lien receives funding from the NASA Citizen Science Seed Funding Program. When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes ...
