"Mysterious Activity Detected in the Milky Way's Dark Matter Halo"

Scientists have observed that stars on the outskirts of the Milky Way are moving more slowly than expected, indicating a potential discrepancy in the distribution of dark matter within the galaxy. Recent measurements using the Gaia mission and APOGEE telescope suggest that the galaxy's dark matter halo may be "cored," with less dark matter in the center than previously thought. This challenges existing models of galaxy formation and raises questions about the nature of dark matter and its influence on the movement of stars within the Milky Way.
