New research suggests that Crater II, one of about 50 tiny galaxies surrounding the Milky Way, may consist of dark matter particles that interact with each other. This discovery, credited to ESA/Gaia/DPAC, is part of ongoing efforts to understand the composition and behavior of dark matter in the universe. Crater II's potential dark matter interactions could provide valuable insights into the fundamental nature of dark matter, which remains one of the most elusive components in astrophysics.
