When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

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, ...

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 ...

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 ...

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 ...

July 25 (UPI) --Scientists have announced a never-before-seen energy peak that resulted from the largest gamma ray burst in history, NASA announced Thursday. The brightest-of-all-time gamma ray burst, ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

New data on the gamma-ray burst "GRB 221009A", observed in October 2022, confirm theoretical models suggesting that these bursts of exceptionally intense electromagnetic waves generate ...

Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The gamma-ray burst (GRB) designated GRB 250702B set itself apart from other explosive bursts of ...
