Supernovae that hit the most distant and thus oldest stars have been discovered by astronomers with the help of the James Webb Space Telescope (JWST).
About 2 billion years after the Big Bang, the explosion that shook the universe marked the death of just one such monster star. Space.com.
The supernova, which was detected as part of the JWST Advanced Deep Extragalactic Survey (JADES) program, could help scientists add more detail to the cosmic picture of the life and death of stars that they are currently building. are
Designated AT 2023adsv, the supernova exploded in a massive primordial galaxy about 11.4 billion years ago.
Interestingly, in the local universe, this stellar explosion may be somewhat different from the supernovae that have occurred recently. The high energy explosion in particular seems much more violent.
“The first stars were very different from today’s stars. They were massive, they were hot, and they had There were really big explosions.” Astronomical Society (AAS) in National Harbor, Maryland on Monday (Jan. 13).
He added: “We don’t know how many. [supernovas] JWST will be found, but we can start to push toward the beginnings of these first stars and hope to see them explode.”
