JWST - Cassiopeia A - SNR G111.7-02.1 - NIRCam - Magnification and reconstruction via AI.

This is our version, via our artificial intelligence model, of the image provided by JWST about Cassiopeia A (Cas A) on December 11, 2023 at 01:00 UTC. Following the image of Cassiopeia A seen via MIRI in April 2023, the JWST team offers us a new image of this subject, in high definition via NIRCam (Near-Infrared Camera). This new image reveals intricate details of the rest of the supernova Cassiopeia A (Cas A) and shows the shell of expanding material colliding against the gas released by the star before its explosion.

 

The most striking colours in Webb's new image are the orange and light pink clusters that make up the inner shell of the rest of the supernova. These tiny nodes of gas, consisting of sulphur, oxygen, argon and neon from the star itself, are only detectable with NIRCam's extraordinary resolution and provide researchers with a clue as to how the dying star shattered like glass when it exploded.
