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.

Every time we check in on [Project326], he’s doing something different with X-rays. This week, he has a passive X-ray imager.

The burst seems to have been caused by a highly extraordinary event, but scientists don’t yet know exactly what that could be ...

(CNN) — Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the ...
