"Unraveling the Mystery of the Milky Way's Dark Matter Halo and Star Movements"

Scientists have observed stars moving more slowly than expected at the outskirts of the Milky Way, suggesting a potential discrepancy in the galaxy's dark matter distribution. Recent measurements combining data from the Gaia spacecraft and ground-based telescopes indicate a decline in orbital velocity for stars at distances of about 100,000 light years, implying less dark matter in the galaxy's center than previously thought. This challenges existing models of galaxy formation and calls for further research and simulations to understand the Milky Way's unique dark matter distribution.
