How does antimatter form?

A team of international astrophysicists led by ANU has shown how most of the antimatter in the Milky Way forms.

Antimatter is material composed of the antiparticle partners of ordinary matter when antimatter meets with matter, they quickly annihilate each other to form a burst of energy in the form of gamma rays.
