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 ...

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy ...

Back in October of 2022, astronomers around the world were baffled and awed by the largest gamma-radiation burst we've ever recorded. The burst was so powerful, in fact, that it has been nicknamed the ...

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 ...

April 12 (UPI) --Scientists at Northwestern University said Friday they had confirmed that the cause of the brightest gamma-ray burst ever observed in October 2022 was the destruction of a star, known ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

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 ...
