Mysterious Source of High-Energy Cosmic Radiation Discovered

NASA announced Mysterious Source of High-Energy Cosmic Radiation Discovered.

"The new results show an unexpected surplus of cosmic ray electrons at very high energy -- 300-800 billion electron volts -- that must come from a previously unidentified source or from the annihilation of very exotic theoretical particles used to explain dark matter.

'This electron excess cannot be explained by the standard model of cosmic ray origin,' said John P. Wefel, ATIC project principal investigator and a professor at Louisiana State. 'There must be another source relatively near us that is producing these additional particles.'

According to the research, this source would need to be within about 3,000 light years of the sun. It could be an exotic object such as a pulsar, mini-quasar, supernova remnant or an intermediate mass black hole. "
