Day 5 of the 2025 Space Telescope Advent Calendar: Colorful Stars of All Ages. About 100 million light-years away, spiral galaxy NGC 6000 is home to countless stars across its disc, which is approximately 66,600 light-years wide. The stars toward the center tend to be older and cooler, emitting a more yellow light, seen here in this Hubble image, streaked by lanes of darker gas and dust. Toward the outer arms of the galaxy, the stars are younger, hotter, and more massive, casting an overall bluer hue.
See the full advent calendar here, where a new image will be revealed each day until December 25.
