18-year Hubble observations of Draco dwarf galaxy's stars reveal 3D motion data, providing insights into dark matter.
18-year Hubble Space Telescope observations of Draco dwarf galaxy's stars reveal unprecedented 3D motion data. By combining line-of-sight velocity and proper motions, researchers gain insights into dark matter, the universe's dominant mass component with unknown properties. Studying dwarf galaxies, which have higher dark matter content, can provide valuable information about dark matter's behavior.
