"Webb Space Telescope's Stunning HD View Reveals Hidden 'Green Monster' in Exploded Star"
TL;DR Summary
The James Webb Space Telescope has captured a stunning high-definition image of the supernova remnant Cassiopeia A (Cas A), revealing intricate details and hidden features. The near-infrared image showcases the expanding shell of material colliding with the gas shed by the star before it exploded. The image highlights tiny knots of gas, circular holes within the "Green Monster" (a loop of green light in Cas A's inner cavity), and light echoes from the star's explosion. The image also reveals a large, striated blob known as "Baby Cas A," which is a light echo located about 170 light-years behind the supernova remnant.
