Day 20 of the 2025 Space Telescope Advent Calendar: The Cosmic Cliffs. The James Webb Space Telescope peered inside a region at the edge of a gigantic gaseous cavity within the star cluster NGC 3324. The cluster, about 9,100 light-years away, near the Carina Nebula, is believed to be fairly young, only about 12 million years old.
