    Until the launch of the Alpha Magnetic Spectrometer (AMS) experiment in 2011, scientists had compiled a mere anthill of information about the kinds of charged particles, or cosmic rays, that shoot around the universe. Two short years later, they have amassed an Everest-sized mountain of such information, and are beginning to publish their findings, which could change our concept of the cosmos.

    Using the power and data transmission capabilities of the International Space Station, AMS is circling Earth and sifting through matter, antimatter and other particles that are yet to be confirmed, 365 days a year. Hundreds of scientists from 16 countries are analyzing the mountain of data, hoping to determine what the universe is made of and how it began, looking for clues on the origin of dark matter and the existence of antimatter and strangelets. And if that’s not enough, there's also the information it could provide on pulsars, blazers and gamma ray bursters, and any number of phenomena that have yet to be named.
