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.

An international scientist collaboration, which consists of 15 researchers, claimed that they transformed water into metal. Their innovation is currently a big deal since the approach they used is quite unique.

For the past few years, most researchers and other experts believed that water is an almost perfect insulator under normal conditions. This means that heat and electricity can t easily pass through the liquid substance.
On the other hand, scientists also explained that water could only develop metallic properties if it is under extreme pressure. This can be seen in the videos showing the core of planets, where a molten metallic liquid is found.
Indian astronomers with other scientists spot unique Gamma-ray burst
The burst detected by NASA s Fermi Gamma-ray Space Telescope on August 26, 2020, turned out to be one for the record books the shortest Gamma-ray burst (GRB) caused by the death of a massive star.
New Delhi: A group of astronomers, few of them Indians, have detected a very short, powerful burst of high-energy radiation that lasted for about a second and had been racing towards Earth for nearly half the present age of the universe.

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.
