The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing ...

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The striking image depicted the supermassive black hole at the center of the ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

A new study published on the pre-print server arXiv is shedding fresh light on one of the galaxy’s strangest high-energy ...

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The ...

This artist’s illustration, which shows a high-speed jet of material being launched from a source that is embedded in a very dusty galaxy, depicts GRB 250702B — the longest gamma-ray burst that ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

In 2018, astronomers took the first-ever picture of a black hole, a fascinating and unprecedented glimpse of an event horizon. And as it turns out, the black hole — dubbed M87* and located some 55 ...

"Maybe there are additional mechanisms generating gamma rays that go beyond the interaction of cosmic rays with the surface of the sun." When you purchase through links on our site, we may earn an ...

A newly funded research project combines the theoretical expertise of University of Rochester scientists with the theoretical and experimental capabilities of ELI Beamlines in the Czech Republic.

It's named BOAT because it's "the Brightest Of All Time." It's also the first of its kind to affect our planet's upper ionosphere. When you purchase through links on our site, we may earn an affiliate ...
