Cosmic twist: Ursa Major III is hiding a black hole core, and not dark matter
SMRTR summary
Astronomers discovered Ursa Major III, once thought to be a dark-matter-dominated dwarf galaxy, may actually be a dark star cluster with a core of black holes and neutron stars. Computer simulations show the Milky Way's gravity likely stripped away outer stars over billions of years, leaving heavy invisible remnants that create high mass-to-light ratios without dark matter. This finding could reduce estimates of dark matter in our galaxy and change how we classify these cosmic objects.
