We will tell you about a new study by MIT physicists that suggests that the Milky Way galaxy’s core may contain less dark matter than previously estimated, based on the surprising discovery that stars at the edge of the galaxy travel more slowly than expected.

We will also explain why this is important for understanding the galaxy’s formation and evolution, and how it relates to the ongoing quest to unravel the mystery of dark matter, which makes up about 85% of the matter in the universe, but has not been directly detected yet.

If you are curious about these questions, then you are in the right place. So, buckle up and get ready for a journey to the center and the edge of the Milky Way galaxy, and beyond.
