"Webb Space Telescope's Stunning HD View Reveals Hidden Secrets of Exploded Star"

The James Webb Space Telescope has provided a stunning new high-definition look at the supernova remnant Cassiopeia A (Cas A) in the near-infrared spectrum. The image reveals intricate details of the expanding shell of material from the exploded star, including tiny knots of gas and light echoes. The image also highlights the absence of color in certain regions, indicating the presence of ionized gas and dust. Researchers are particularly intrigued by a large, striated blob called "Baby Cas A," which appears to be a light echo located about 170 light-years behind the supernova remnant.
