Anti-Matter Belt Discovered Around Earth

hydrofix writes: A thin band of antiprotons enveloping the Earth has been spotted for the first time. The find, described in Astrophysical Journal Letters [arXiv], confirms theoretical work that predicted the Earth's magnetic field could trap antimatter. The antiprotons were spotted by the Pamela satellite launched in 2006 to study the nature of high-energy particles from the Sun and cosmic rays. Aside from confirming theoretical work that had long predicted the existence of these antimatter bands, the particles could also prove to be a novel fuel source for future spacecraft — an idea explored in a report for Nasa's Institute for Advanced Concepts.
