Day 18 of the 2025 Space Telescope Advent Calendar: A Spider Among the Stars. About 5,000 light-years away, the Red Spider Nebula is the result of the spectacular final act of a dying star. The James Webb Space Telescope recently imaged this planetary nebula, showing the glowing outer layers of the star—which have been cast off for thousands of years, blasted into space in all directions—against a backdrop of countless other stars in our own galaxy.
See the full advent calendar here, where a new image will be revealed each day until December 25.
