Scientists at Northwestern University said Friday they had confirmed that the cause of the brightest gamma-ray burst ever observed (the circled infrared afterglow and host galaxy pictured 1-2 months ...

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a ...

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 ...

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

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

Gamma-ray bursts (GRBs) are very bright flashes of radiation, that are detected approximately 100 times per year by satellites. For a long time it was a mystery where these flashes originated from and ...

WASHINGTON (Reuters) - About two billion years ago in a galaxy far beyond our Milky Way, a big star met its demise in a massive explosion called a supernova that unleashed a huge burst of gamma rays, ...

A research team led by the Institute of High Energy Physics of the Chinese Academy of Sciences has made a breakthrough discovery. They identified a gamma-ray spectrum line with an energy of up to 37 ...

On the morning of October 9, 2022, multiple space-based detectors picked up a powerful gamma-ray burst (GRB) passing through our Solar System, sending astronomers around the world scrambling to train ...

April 12 (UPI) --Scientists at Northwestern University said Friday they had confirmed that the cause of the brightest gamma-ray burst ever observed in October 2022 was the destruction of a star, known ...
