"Discovery of New Star System Orbiting Milky Way"
Astronomers have discovered UMa3/U1, the faintest star system ever observed orbiting the Milky Way galaxy, located 30,000 light-years away in the constellation Ursa Major. The system, containing a mere 60 stars spanning about 10 light-years across, poses a mystery as to whether it is a true dwarf galaxy or a star cluster, with the role of dark matter being a key factor. This discovery challenges our understanding of galaxy formation and offers the potential to revolutionize our understanding of the universe's structure.
