A supernova caused the BOAT gamma ray burst, JWST data confirms But astronomers are puzzled by the lack of signatures of expected heavy elements. Jennifer Ouellette – Apr 12, 2024 5:00 am ...

Some scientists think they’ve found the signature of a supernova buried in the afterglow of the brightest gamma-ray burst (GRB) ever observed. Others aren’t so sure.

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 ...

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

Few things in space are as bright as a supernova, but recently astronomer captured a flash out in the cosmos so great their ...

Long gamma-ray burst stems from neutron star merger, not usual supernova explosion. Jennifer Ouellette – Dec 7, 2022 6:44 pm | 54 Artist’s impression of GRB 211211A.

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 ...

To study the effects of last year’s gamma ray burst on Earth, Dr. Ubertini and his colleagues looked for signals at the top of the ionosphere using data from the China Seismo-Electromagnetic ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

While the relative proximity of a burst as powerful as GRB221009A is a boon to science, astronomers are not keen to see a gamma-ray burst much closer to Earth. Especially not in our galaxy.

The first analyses of that remarkable event provides the strongest evidence yet that supernovas and gamma-ray bursts might be linked. IE 11 is not supported.

Back in 2017, they discovered that short gamma-ray bursts—those lasting just a couple of seconds—generated the hot, dense, and neutron-rich conditions necessary to forge heftier members of the ...
