The James Webb Space Telescope has spotted one of the earliest and most distant supernovas, marking the death of a stellar monster 20 times the mass of the sun.

The James Webb Space Telescope (JWST) has captured the first exquisite images of an interstellar patch of sky, about 11,000 light-years away in the constellation Cassiopeia.

The shells of carbon-rich dust are expanding outward into space at the breakneck velocity of 1,600 miles per second.

A cosmic object spotted by the James Webb Space Telescope has flummoxed astronomers. Now, a research team has studied hundreds of these "little red dots" and found clues about their identity.
