Hints of lightweight dark matter particle found in space - space - 28 October 2010 - New Scientist

Hints of lightweight dark matter particle found in space: In a new analysis of two years of data collected by NASA's orbiting Fermi telescope, the team has found evidence of excess gamma-ray light emitted from the inner 100 light years of the galaxy.

They say the light is too bright, energetic, and confined to be explained by known gamma-ray sources. "We're at a point where we have a clear signal of what we think could be dark matter, without any alternative explanation," Hooper says.
