A matter-antimatter annihilation due to an atom of antihydrogen in the ATHENA experiment at CERN. The antiproton produces four charged pions (yellow), whose positions are given by silicon microstrips (pink) before depositing energy in CsI crystals (yellow cubes). The positron also annihilates to produce back-to-back gamma rays (red) (Image: CERN)
