Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.

On Oct. 9, 2022, Swift’s X-Ray Telescope captured the afterglow of the brightest gamma-ray burst every recorded, called GRB 221009A. Credit: NASA/Swift/A. Beardmore (University of Leicester) ...

Gamma rays are much shorter in wavelength than visible light, and carry a lot more energy—so much energy, ... Astronomers have sent x-ray telescopes into orbit to scan the sky, ...

Gamma-ray bursts are the brightest explosions the cosmos has to offer, besides the Big Bang—the explosion that happened 13.77 billion years ago that marks the beginning of time. The BOAT was ...

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Going beyond current laser technology—which includes coherent X-ray lasers, just next to gamma rays on the electromagnetic spectrum—means scientists need to investigate what happens when dense ...

In addition to its brightness, October's gamma-ray burst is also only the seventh GRB to display X-ray rings, with triple the number ever seen. The echoes came from dust located between 700 and ...

NASA said that GRB 221009A is only the 7th gamma-ray burst we’ve detected that creates these x-ray rings. The echoes came from dust located between 700 and 61,000 light-years away. The AAS ...

The incredible blast, officially dubbed GRB 221009A, was first spotted by gamma-ray and X-ray telescopes, including NASA's Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory ...
