Using the James Webb Space Telescope (JWST), astronomers have discovered one of the most distant and therefore oldest supernovae ever seen.. This explosion, which rocked space some 2 billion years after the Big Bang, marked the death of just such a giant star..

Supernovae occurred in different ways in the early Universe. Especially when the star that exploded was a stellar monster whose mass was 20 times the mass of the Sun. This supernova, discovered by JWST's Advanced Deep Extragalactic Exploration (JADES) program, could help scientists add more detail to the cosmic picture of stellar life and death they are now building, writes Space.

The supernova, designated AT 2023adsv, erupted about 11.4 billion years ago in a massive early galaxy.

Interestingly, this stellar explosion may be somewhat different from the supernovas that have recently occurred in our Universe. In particular, the high-energy explosion seemed to be too strong.

" They were massive, they were hot, and they had truly gigantic explosions," The scientist also added that they cannot know how many supernovae the JWST will find, but this find may help them advance to the beginning of these first stars and hope to see them explode..
