"Webb Space Telescope Reveals Stunning High-Definition Images of Cassiopeia A Supernova Remnant"

The Webb Space Telescope has captured a high-resolution image of the supernova remnant Cassiopeia A, revealing intricate details of the expanding shell of material from the star's explosion. The image shows clumps of gas in bright orange and light pink, composed of sulfur, oxygen, argon, and neon. The debris includes tiny filaments comparable to shards of glass, providing new insights into the star's explosion. This is the second image of Cassiopeia A taken by Webb, with the invisible wavelengths of light captured by the telescope shifted into the visible spectrum.
