February 9, 2013 An artist's concept shows a vast halo of dark matter surrounding the disk of our home galaxy, the Milky Way. Dark matter produces no detectable energy but reveals its presence by tugging on visible stars, gas, and other matter. Dark matter, which may take the form of heavy subatomic particles, far outweighs all the visible matter in the Milky Way and the rest of the universe. [ESO/L. Calçada]
