JWST Revisits Famous Supernova Remnant Cassiopeia A And Finds Even More Mysterious FeaturesCassiopeia A as seen by NIRCam (Near-Infrared Camera), showing the expanding shell of material slamming into the gas shed by the star before it exploded. The most noticeable colors are clumps of bright orange and light pink that make up the inner shell of the supernova remnant. These tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself, are only detectable by NIRCam’s exquisite resolution.

Gorgeous JWST Image Of Cassiopeia Reveals Hard-To-Explain DetailsOn the remnant’s exterior, particularly at the top and left, lie curtains of material appearing orange and red due to emission from warm dust. This marks where ejected material from the exploded star is ramming into surrounding circumstellar material. Interior to this outer shell lie mottled filaments of bright pink studded with clumps and knots. This represents material from the star itself, and likely shines due to a mix of various heavy elements and dust emission. The stellar material can also be seen as fainter wisps near the cavity’s interior. A loop represented in green extends across the right side of the central cavity. Its shape and complexity are unexpected and challenging for scientists to understand.
