It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

March 29 (UPI) --A gamma-ray burst, which lit up our galaxy last October, was the "brightest burst" ever seen and a once-in-10,000-year explosion, according to NASA. Astronomers have been studying the ...

On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...

Astronomers have spotted a bright gamma-ray burst that upends previous theories of how these energetic cosmic eruptions occur. For decades, astronomers thought that GRBs came in two flavors, long and ...

On Oct. 9, 2022, the orbiting Swift and Fermi gamma-ray detectors observed the brightest gamma-ray burst (GRB) ever seen: GRB 221009A. Astronomers around the world quickly responded by turning as many ...

The brightest gamma ray burst ever detected recently reached our planet. It’s 70 times longer than any other burst we’ve spotted, and effectively blinded our instruments when it hit. Researchers say ...

A bright flash of gamma rays from the constellation Boötes that lasted nearly one minute came from a kilonova, as we described in a new paper. This finding challenges what astronomers know about some ...

Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The gamma-ray burst (GRB) designated GRB 250702B set itself apart from other explosive bursts of ...

A peculiar cosmic explosion first detected by NASA’s Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision ...

In its first five years in orbit, NASA’s Swift satellite has given astronomers more than they could have hoped for. Its discoveries range from a nearby nascent supernova to a blast so far away that it ...
