A group of 60 ultra-faint stars orbiting the Milky Way could be a new type of galaxy never seen before | Trending Viral hub


Astronomers have discovered the faintest and lightest satellite galaxy ever found: a tiny, tightly knit group of stars following the Milky Way. The peculiar discovery could represent a new class of incredibly faint, dark matter-dominated star systems that have eluded detection until now.

The new star system, provisionally named Ursa Major III/Unions 1 (UMa3/U1), resides in the Ursa Major constellation, about 30,000 light years from the Sun. It is the most recent addition to our galaxy’s assortment of at least 50 satellite galaxies. Even the smallest of these galaxies host thousands to billions of stars.
