NASA’s Webb Stuns With New High-Definition Look at Exploded Star (IMAGE)
Caption
NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova’s inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star itself. A large, striated blob at the bottom right corner of the image, nicknamed Baby Cas A, is one of the few light echoes visible NIRCam’s field of view. In this image, red, green, and blue were assigned to Webb’s NIRCam data at 4.4, 3.56, and 1.62 microns (F444W, F356W, and F162M, respectively).
