Day 15 of the 2025 Space Telescope Advent Calendar: A Turbulent Lagoon. Back in 2018, to celebrate its 28th anniversary in space, scientists pointed the Hubble Space Telescope at the Lagoon Nebula, a roiling cloud of gas and dust about 4,000 light-years away, to capture this image, which shows just a small section of a much larger star-forming region.
See the full advent calendar here, where a new image will be revealed each day until December 25.
