A community portal about Antimatter with blogs, videos, and photos. According to Wikipedia.org: In particle physics, antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc 2. This gives rise to high-energy photons or other particle–antiparticle pairs. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.
Positrons, the antimatter equivalent to electrons, were detected in gamma ray bursts during lightning storms. A satellite dispatched to scout out high-energy gamma rays streaming from the cosmos found that not only were flashes of gamma rays oddly close to home, but they were also powerful enough to annihilate matter.

You probably think of antimatter as the stuff of science fiction or as something being created in particle accelerators. However, antimatter might be closer and more common than you think. The Fermi Gamma-Ray Space Telescope scans the heavens for gamma rays, but it has also detected gamma ray flashes from terrestrial storms. Two of these events carried the signature associated with the decay of positrons, one form of antimatter.The terrestrial...

AMESN writes "The Fermi Gamma-ray Space Telescope, launched last year, detects gamma rays from light years away, but recently it detected gamma rays from lightning on Earth. And the energy of the gamma rays is specific to the decay of positrons, which are the antimatter flavor of electrons. Finding antimatter in lightning surprised researchers and suggests the electric field of the lightning somehow got reversed."Read more of this story at...

Personally, I think this has to do with thunderstorms being essentially linear accelerators, vertical SLAC’s if you will. Huge charge differentials from top of cloud to bottom makes for a nice particle slingshot. There’s plenty of opportunity for antimatter (positrons) to be created in energetic collisions from particles coming out of the tops of thunderstorms. [...]
