NASA's James Webb gave a stunning look at the death throes of a star, capturing details JWST captured an image of an exploded star in unprecedented detail. It shows previously unseen details of a shell of material hitting the gas shed by the star. NASA's James Webb Space Telescope (JWST) has captured an image of Cassiopeia A (CasA), an effervescent structure left by the dying breath of a star that exploded from Earth's perspective. Using its powerful near-infrared camera (NIRCam), JWST peered through the vast remnants of Cas A to reveal a never-before-seen pattern of the extended shell of material that rumbles around the city shed by the star. Focusing on these designs can help us understand how stardust spread through the universe and how it eventually helped create life. "With NIRCAM's mission, we can now understand how a collapsed star breaks up completely when it explodes, comparing the fibers to tiny pieces of glass," Purdue...
