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.

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

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

Australia's SpIRIT nanosatellite is the first space telescope funded by the Australian Space Agency to carry a scientific ...

(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 ...

Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...
