Cosmic Rays Hunted Down: Physicists Closing in on Origin of Mysterious Particles

A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type of telescope began to come online physicists weren't sure where the "cosmic rays" came from or how they were generated.
