The James Webb Space Telescope captured stunning new images of Cassiopeia A, a star that exploded in a supervova event and for years has dazzled astronomers and sky viewers.

A beautiful supernova remnant, Cassiopeia A, was recently imaged by the James Webb telescope. See how the observation compares to a previous MIRI image.
