It Took 100 Years, but We May Finally Have ‘Seen’ Dark Matter

Summary

A NASA telescope has possibly found dark matter, an elusive substance that scientists have been trying to identify for nearly a century. Researchers from the University of Tokyo used data from the Fermi Gamma-ray Space Telescope to find gamma rays that could indicate the presence of dark matter at the center of the Milky Way.

Key Facts

  • Dark matter is a substance believed to hold galaxies together but it cannot be directly seen or measured.
  • A NASA telescope called the Fermi Gamma-ray Space Telescope detected gamma rays possibly linked to dark matter.
  • The gamma rays observed match predictions of how dark matter particles might behave when they collide and annihilate each other.
  • Researchers focused on a region called the halo of the Milky Way, which was less studied before.
  • The detection of gamma rays supports the theory that dark matter may be "WIMPS," or Weakly Interacting Massive Particles.
  • The discovery may lead to identifying a new elementary particle not in the current physics model.
  • Scientists need additional data and independent verification to confirm these findings.
