Since its launch on December 25, 2021 (quite a Christmas present!), the James Webb Space Telescope (JWST) took the sharpest and most detailed images of the Universe, surpassing even its predecessor, the venerable The Hubble Space Telescope! But what’s particularly exciting are the kinds of sightings we can expect, where the JWST will use its …

Artist’s impression of a gamma-ray burst just after the collapse of its progenitor star. Credit: Nuria Jordana-Mitjans/University of Bath Scientists determine that a gamma-ray burst detected on Earth was caused by a space explosion that occurred less than 900 million years ago. On September 5, 2021, light from a Highly Energetic Gamma Burst (GRB) – …
According to the most widely accepted theory of star formation (the nebular hypothesis), stars and planets form from huge clouds of dust and gas. These clouds undergo gravitational collapse at their center, resulting in the birth of new stars, while the rest of the matter forms disks around it. Over time, these disks become ring …

‘Extreme stripping action’ led to disorderly birth of South Ring Nebula, Webb image reveals Nasa Orsola DeMarco, Macquarie University When the first five images from the James Webb Space Telescope (JWST) were unveiled, one of them stared at me with two eyes. It was an image of the South Ring Nebula, NGC3132, and right in …

Using data from India’s SARAS3 radio telescope, researchers led by the University …
Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers identified the galactic foci of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.
