WASHINGTON (Reuters) - About two billion years ago in a galaxy far beyond our Milky Way, a big star met its demise in a massive explosion called a supernova that unleashed a huge burst of gamma rays, ...

An astounding gamma-ray burst, dubbed GRB 221009A, continues to amaze even though it has been more than a year since it was detected. Scientists from Italy have recently published a study that shows ...

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 incendiary ...

On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst ...

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 ...
