A powerful explosion in space was detected on Oct. 19 by astronomers at NASA's Swift Observatory, which detects gamma-ray bursts likely caused by supernova events in the cosmos.

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions seen since the Big Bang.

The researchers believe that the centers of such old galaxies are cloaked in vast amounts of gas and dust, which could obscure the gamma-ray burst. That would mean the 2019 event was an exception.

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.

Called a gamma-ray burst (GRB), the massive explosion emitted flares of high-energy X-ray and gamma radiation and was likely spurred by a gigantic star’s collapse, according to Inverse’s Kiona ...

The explosion, observed on March 7, was the second brightest gamma-ray burst ever witnessed by telescopes in more than 50 years of observations, over one million times brighter than the entire ...

The signal from this burst, experts found, had been traveling for about 1.9 billion years before reaching Earth. ... 2022, was a gamma-ray burst, the most powerful kind of explosion.

The high-energy emission known as a gamma-ray burst (GRB) – the most powerful type of explosion seen in our universe since the Big Bang – likely represents the moment a dying star collapsed ...

The next hour is marked by the passing whine of drones, the responding air defence fire and continual explosions. Some are ...

The explosion was a gamma-ray burst that scientists believe was triggered by a supernova, or the death of a star, that gave way to a black hole. The event, named GRB 221009A, ...
