"Slower Star Travel at Milky Way's Edge Suggests Lower Dark Matter in Galaxy's Core"

Physicists at MIT 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 be lighter in mass and contain less dark matter than previously thought. The findings are based on analysis of data from the Gaia and APOGEE instruments, and the team's study has been published in the Monthly Notices of the Royal Society Journal. This unexpected result may lead to a reconsideration of the state of equilibrium of our galaxy and could have deep repercussions in understanding the distribution of dark matter in the Milky Way.
