"JWST Reveals Stunning Images of Cassiopeia A Supernova Remnant"
The James Webb Space Telescope (JWST) has captured a stunning near-infrared image of Cassiopeia A, a famous supernova remnant in the Milky Way. The image reveals new details and features, including a stripey blob called Baby Cas A, which is actually a light echo caused by Cas A's light hitting a distant clump of dust. The image also shows the inner shell of the explosion, resembling shards of glass, and the smoky outer shell expanding into interstellar space. Scientists are gaining transformative insights into how the star exploded and are studying the dynamics of the remnant.
