Andromeda XXXVI (And 36) is shown in red in this image. It's one of many dwarf galaxies found around Andromeda, or M31, in the center of the image. And 36 is about 12.5 billion years old and is about 390,000 light years away from Andromeda. Image Credit: Sakowska et al. 2026. A&A.

Astronomers have discovered an extremely low-mass and dim dwarf galaxy around Andromeda. Called And 35, it's an Ultra-Faint Dwarf Galaxy (UFDG) and so far, the researchers have detected only 46 of its stars. Lambda-CDM predicts that there should be many UFDGs around galaxies like Andromeda and the Milky Way, so finding more of them is important.
