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, ...

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 ...

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 ...

In October, scientists were stunned by the detection of the brightest gamma ray burst, intense explosions observed in distant galaxies, known to man. Dazzled by its striking flash, scientists aptly ...

Gamma-ray bursts are the most powerful explosions in the universe. They emit most of their energy in gamma rays, light which is much more energetic than the visible light we can see with our eyes. In ...

Astronomers at Rice University in Houston have discovered that the rate at which a gamma-ray burst cools might be used to calculate the distance of that burst. Their findings are being presented today ...

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 ...
