"Galactic Core's Reduced Dark Matter Leads to Slower Star Travel at Milky Way's Edge"

MIT physicists have found that stars further out in the Milky Way galaxy are traveling more slowly than expected, suggesting that the galaxy's gravitational core may contain less dark matter than previously estimated. By analyzing data from the Gaia and APOGEE instruments, the team observed a surprising dip in the rotation curve at the galaxy's outer edge, indicating a lighter galactic core. These findings challenge previous assumptions and may lead to a reevaluation of the distribution of dark matter within the Milky Way.
