Shooting towards Earth for as long as nearly half the present age of the universe, the burst or signal is said to have beeped for less than a second â short, yet enough to make its powerful presence felt.
The detection challenges astronomers current understanding of gamma-ray bursts and where they come from.
A whisper of an extraordinary cosmic event reached our Earthly ear last year, leading the qualified on a quest to decipher it. Now, eleven months later, we learn about the cosmic catch.

Bengaluru: Once upon a time, billions of years ago, a star died. It let out a pulse of extremely high energy a gamma ray burst (GRB), as the astronomers call it that was detected on Earth just last year. Lasting less than a second, it was the shortest of its kind ever observed.
And it appears to have challenged some existing models that govern the way these bursts are seen.
Astronomers looking through NASA’s Fermi Gamma-ray Space Telescope observed a pulse of extremely high energy in the form of a GRB on 26 August 2020. The GRB, the astronomers say, is the shortest known to have been caused by the death of a star.
