Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth. By Laura Baisas Published Jun 23, 2023 9:00 AM EDT Get the Popular Science daily ...

The researchers believe that the centers of such old galaxies are cloaked in vast amounts of gas and dust, which could obscure the gamma-ray burst. That would mean the 2019 event was an exception.

Radiation from the explosion — a gamma-ray burst (GRB) known as GRB 221009A — swept over Earth on Oct. 9, 2022. It saturated gamma-ray detectors on multiple space telescopes, earning the ...

And as it turns out, the black hole dubbed M87*, some 55 million light-years away, also let out a massive belch of gamma rays while scientists from the Event Horizon Telescope team, ...

The team combined 13 years of gamma ray data from NASA's Fermi Large Area Telescope to analyze the cosmic gamma-ray background. The researchers found a gamma-ray dipole, but its peak was located ...

According to Dr. Ubertini, if the gamma ray burst was a million times larger, it could have ionized enough ozone to weaken the protective barrier for days or months. But the chances of that ...

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.
