Dark Matter Discovered Near Solar System?

Posted by Soulskill on from the near-being-a-relative-term dept.

gpronger writes "The ATIC (Advanced Thin Ionization Calorimeter) has potentially discovered the presence of dark matter close (only 3000 light-years) to our solar system. The system detected a large-amount of high energy cosmic rays which match the theoretical signature of dark matter annihilating itself. The universe is believed to be composed of about 25% dark matter, but there has been little evidence of it. This discovery, if correct, would be the first." The paper was published in Nature , but it requires a subscription to see beyond the abstract.

    If this would be the first evidence how can we already have a little evidence of it?
