Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

The international CTAO LST Collaboration has released remarkable findings from observations of GRB 221009A—the brightest ...

Northwestern University scientists said Friday they had confirmed that the cause of the brightest gamma-ray burst ever observed in October 2022 was an exploding star, known as a supernova, 2.4 ...

Dubbed the B.O.A.T. ("brightest of all time"), gamma ray burst GRB221009A was discovered by JWST in 2022. What caused it is unexpected.

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 brightest gamma-ray burst yet recorded gave scientists a new high-energy feature to study. Learn what NASA’s Fermi mission saw, and what this feature may be telling us about the burst’s ...

The gamma-ray burst (GRB) known as the Brightest Of All Time (BOAT) had an emission line in its afterglow, the first time one has been detected with confidence in any GRB.

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

“This event is particularly exciting because some had hypothesized that a luminous gamma-ray burst like the B.O.A.T. could make a lot of heavy elements like gold and platinum,” said study co ...

The brightest gamma-ray burst ever recorded was caused by the collapse and explosion of a massive star, astronomers have discovered. Dubbed the B.O.A.T. (‘brightest of all time’) a team of ...

The brightest gamma-ray burst (GRB) ever recorded, resulting from the collapse and subsequent explosion of a massive star, was first detected by space observatories in October 2022. Now, an ...
