Snapshots of colorful galaxies and planets show that the beauty of our universe knows no bounds, and recent images of glowing space gas and dust captured by NASA are no exception. The James Webb Space Telescope (JWST) has caught yet another visual spectacle, depicting layers of interstellar material illuminated by a supernova in a phenomenon known as a thermal light echo.

Getting a glimpse of the brilliant scene through JWST, a team at NASA created a 3D scan of the interstellar material that displays its intricacies in tremendous detail. Now, astronomers are able to zoom into a piece of the universe that has never been seen before.
