Unexpected Star Movements Challenge Current Understanding of the Milky Way

New findings suggest less dark matter in the galaxy's core, contradicting previous assumptions and measurements.

  • Stars at the edge of the Milky Way are moving more slowly than expected, suggesting a different structure of the galaxy than previously thought.
  • The slower movement of these stars implies that the core of the Milky Way may contain less dark matter, making it lighter in mass than initially assumed.
  • Dark matter, which does not interact with regular matter or the electromagnetic field except by gravity, is thought to comprise around 27% of the known universe.
  • The findings contradict previous measurements and assumptions about the distribution of dark matter within our galaxy.
  • The research team plans to use high-resolution computer simulations to model different distributions of dark matter within our galaxy to better understand these findings.
