Cosmic ray detector confirms hints of dark matter

Space station-based instrument records high amount of antimatter seen in earlier experiments

A $2-billion experiment on the International Space Station has released the first data from its unprecedented census of the charged subatomic particles whizzing by Earth. Although the results, presented April 3 at a seminar at CERN in Geneva, largely confirm previous observations, researchers hope they will lead to discovering the identity of dark matter, an invisible form of matter that outweighs normal matter in the universe by more than 5 to 1.
