JWST - Cassiopeia A - SNR G111.7-02.1 - MIRI - 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). It is a supernova remnant located about 11,000 light years from Earth in the constellation Cassiopeia. This new image uses data from Webb's MIRI (Mid-Infrared Instrument) to reveal Cas A in a new light.

 

Outside the remnant, there are curtains of material that appear orange and red due to the emission of hot dust. This marks the point where the material ejected from the exploded star collides with the surrounding circumstellar material.

 

Inside this outer shell are bright pink mottled filaments, dotted with clumps and knots. This is material from the star itself, which probably glows from a mixture of various heavy elements and dust emission. The stellar material is also visible in the form of fainter clumps within the cavity.

 

A ring depicted in green extends to the bottom right offset from the centre. Its shape and complexity are unexpected and challenging for scientists to understand.

 

North is in the top right-hand corner.
