Day 13 of the 2025 Space Telescope Advent Calendar: A Sea of Galaxies. The James Webb Space Telescope pointed its Near-Infrared Camera toward the galaxy cluster MACS J1149.5+2223 and captured this image of hundreds of galaxies at varying distances and of different sizes, shapes, and colors—showing only a small section of the cluster.
See the full advent calendar here, where a new image will be revealed each day until December 25.
