Pulsar found leaking antimatter

Neutron stars are one possible suspect responsible for an abundance of positrons in the Milky Way. Now astronomers have caught one red handed.

Earth is getting hit by too much anti-matter

Astronomers think that Earth is showered by 'anti-electrons' because of pulsars, but there are more of these particles coming at us than there should be.
