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 ...

Astronomers have begun to unleash the full potential of artificial intelligence (AI) to unravel the deepest mysteries of the universe. Recent studies have harnessed the power of multiple AI machine ...

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 ...

Two neutron stars begin to merge in this artist’s concept, blasting jets of high-speed particles. Collision events like this one create short gamma-ray bursts. Credit: NASA’s Goddard Space Flight ...

The source of a huge burst of radiation from deep space that hit Earth in 2023 likely was one of the rarest and most bizarre objects in the universe: a magnetar. NASA Spitzer, Hubble and Chandra space ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

WASHINGTON – A powerful stellar explosion detected March 19 by NASA’s Swift satellite has shattered the record for the most distant object that could be seen with the naked eye. The explosion was a ...

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 ...

The most powerful events in the known universe—gamma-ray bursts (GRBs)—are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the ...
