Mysterious Glow in Milky Way Could be Evidence of Dark Matter

Researchers from Johns Hopkins University may have found a clue to prove the existence of dark matter.

A diffuse glow of gamma rays near the center of the Milky Way has puzzled researchers for decades, with two competing theories: colliding particles of dark matter or quickly spinning neutron stars.

The excess gamma light could become the first proof that dark matter exists, if it's not from dying stars.

According to new research published in Physical Review Letters, both theories are equally likely.
