Summary:
Through a Hubble Space Telescope analysis of stars that have undergone gravitational microlensing, astronomers have collected strong evidence that microlensing events are caused by compact dark matter in the halo of the Milky Way.

SAN DIEGO, Calif. (Jan. 8, 2001) –- Through a Hubble Space Telescope analysis of stars that have undergone gravitational microlensing, astronomers have collected strong evidence that microlensing events are caused by compact dark matter in the halo of the Milky Way. The findings will be presented today by Cailin A. Nelson and Dr. Kem H. Cook of the Lawrence Livermore National Laboratory on behalf of the Massive Compact Halo Objects (MACHO) collaboration during the annual meeting of the American Astronomical Society in San Diego, Calif.
