Illustration of Antimatter/Matter Annihilation

Antimatter is made up of elementary particles that have the same masses
as their corresponding matter counterparts but the opposite charges and
magnetic properties. This illustration shows what happens when a
particle of antimatter collides with one of matter. The particles
annihilate each other and produce energy according to Einstein's famous
equation, E=mc
2, mostly in the form of gamma rays, which scientists are
looking for using the Compton observatory. Secondary particles are also
produced. This annihilation has not been seen in the Bullet Cluster.
