Dark Matter Detected? Researchers See 'Possible Signal' | Video

Odd X-ray photon blasts from the Andromeda Galaxy, the Perseus cluster and our own Milky Way correspond to theoretical predictions of Dark Matter, which may make up 80% of our universe’s mass. Scientists from the European University École Polytechnique Fédérale de Lausanne (EPFL) say this could be long sought evidence for the mass needed to understand the structure of the cosmos.
