James Webb Telescope uncovers onion-like layers in dust around exploded star Cassiopeia A.

The James Webb Space Telescope (JWST) has revealed detailed images of interstellar dust near Cassiopeia A, a star that exploded in the 1670s. The telescope captured light echoes showing layered dust structures resembling onions, with dense sheets, knots, and swirls. These findings offer new insights into the magnetic field lines and turbulence of the interstellar medium, enhancing our understanding of space between stars.
