Clumps in the Milk(y Way)?!

In Antarctica, a balloon-borne instrument has found evidence of a possible large clump of mysterious so-called dark matter relatively close to our solar system... It detected an unexpected amount of very high energy cosmic ray electrons coming from an unknown source within about 3,000 light years of the solar system.

One explanation is that the electrons may have been spawned as dark matter particles collided with one another, triggering their mutual annihilation, according to Louisiana State University physics professor John Wefel.

It is invisible. And poorly understood.

The scientists said it is possible that the electrons detected in this research may have been produced by a more conventional source -- perhaps a spinning neutron star called a pulsar that emits a beam of radiation, a medium-sized black hole or the remnants of a bygone supernova.

This is CRAZY and incredibly fascinating.
