NASA’s JWST Uncovers One of the Earliest ‘Truly Gargantuan’ Supernovas

Astronomers have identified one of the earliest and most distant supernovae capable of destroying stars with assistance from the James Webb Space Telescope (JWST). This explosion, which shook the universe, signifies a massive star’s demise approximately 2 billion years after the Big Bang.

This supernova, identified as part of the JWST Advanced Deep Extragalactic Survey (JADES) initiative, can potentially enhance scientists’ understanding of the cosmic lifecycle of stars.

Named AT 2023adsv, the supernova occurred approximately 11.4 billion years ago in a significant early galaxy.

Interestingly, this stellar explosion may differ somewhat from more recent supernovas within our local universe. Notably, the high-energy event appears to have been exceptionally violent.

“The initial stars were significantly different from the stars we see today.

They were large, extremely hot, and produced truly enormous explosions,” stated David Coulter, a member of the JADES team and a researcher at the Space Telescope Science Institute (STScI), during the 245th meeting of the American Astronomical Society (AAS) in National Harbour, Maryland, on Monday (January 13).

He continued, “While we are unsure how many supernovas the JWST will discover, we can begin to delve into the origins of these first stars and hope to witness their explosions.”
