Astro-Physicists Discover Anti-matter Trapped in Earth's Magnetic Field

Previous theoretical predictions by solar scientists have asserted that the Earth’s geo-magnetic field, or magnetosphere, should be capable of trapping or containing anti-matter. Now comes confirmation, via the international PAMELA satellite mission, of a narrow band of anti-protons trapped between the inner and outer Van Allen radiation belts, part of the Earth’s magnetosphere. The discovery constitutes “the most abundant source of antiprotons near the Earth.” The trapped anti-matter may one day provide a fuel source for spacecraft.
