Publisher's Summary

High-energy blips of radiation known as gamma rays seem to be streaming from the center of the Milky Way in excess. Some scientists have proposed that dark matter could be the cause of that overabundance. Particles of dark matter — an invisible and unidentified substance that makes up the bulk of the matter in the cosmos — could be annihilating in the center of the galaxy, producing gamma rays.
