First data released from the Alpha Magnetic Spectrometer

The first published results from the Alpha Magnetic Spectrometer (AMS), a major physics experiment operating on the International Space Station, were announced today by the AMS collaboration spokesman, Nobel Laureate Samuel Ting. The result is the most precise measurement to date of the ratio of positrons to electrons in cosmic rays. Measurements of this key ratio may eventually provide the world with our first glimpse into dark matter.
