Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope ...

The latest image shows a central structure of inner ejecta similar to a keyhole. Clumpy gas and dust pack up the center that is ejected by the supernova explosion. According to NASA, the dust is so ...

The James Webb Space Telescope has captured some bizarre imagery of an exploding star that, for some reason, kept repeating itself. In a press release, NASA said that new Webb images of what ...

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...
