A giant explosion that lit up the sky didn't just rock the cosmos – it absolutely rattled our understanding of the Universe's most powerful outbursts. The gamma-ray burst (GRB) recorded on 2 July 2025 ...
Cambridge, MA – Gamma-ray bursts are the most powerful explosions in the universe, emitting huge amounts of high-energy radiation. For decades their origin was a mystery. Scientists now believe they ...
In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A. Now, a ...
When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

Astronomers missed a space explosion as powerful as a billion suns — until they spotted its echo
A cosmic explosion with an energy equivalent to the output of a billion suns went unnoticed by astronomers until they caught the "echo" of this gamma-ray burst.
The gamma ray burst nicknamed the BOAT, or brightest of all time, was so powerful — and the data it yielded so overwhelming — that it still has scientists’ heads spinning in its afterglow nearly two ...
In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...
It was only last October that telescopes spotted a gamma ray burst—caused by the collapse of a black hole—that was so ...
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 ...
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 ...
