James Webb telescope discovers most distant supernova ever seenThe James Webb Space Telescope has spotted a supernova dating to just 1.8 billion years after the Big Bang, as well as 80 others in the early universe. The ancient explosions could help scientists figure out the mysteries of how the cosmos evolved.

James Webb telescope finds origins of the biggest explosion since the Big Bang — revealing a new cosmological mysterySeen in 2022, a gamma-ray burst nicknamed the BOAT is believed to be the brightest explosion ever witnessed by humanity. But the James Webb Telescope's search for its origins has only thrown up more questions.
