Gamma-ray bursts typically emit as much energy in a few seconds as an entire galaxy of stars will emit in years. Think about this: a single sudden explosion, which becomes as bright as the ...

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a ...

That same instrument, the Event Horizon Telescope (EHT), has now witnessed the same black hole erupt with a powerful and unexpected explosion ... light called gamma rays. Not only was this ...

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand ... and others have investigated this explosion using a slew of ground-based and space-based ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

Four billion light years away from Earth, there was an explosion so big that it generated more energy than the Sun can generate in its entire 10 billion-year lifespan. Gamma rays are some of the ...

The burst was linked to GRB 240315C, a gamma-ray burst, but its characteristics—like a 6-minute delay between X-rays and gamma rays—challenge existing theories of GRB formation. Weimin Yuan, ...

"Gamma-ray bursts rank among the universe's most violent explosions, usually generated by the explosion of massive stars," said Liu Yuan, a research fellow at the National Astronomical ...

The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however ...
