Now, an international research team looking over four years of data from the European Space Agency's International Gamma Ray Astrophysics Laboratory (INTEGRAL) satellite has pinpointed the apparent culprits.
Their new findings suggest these positrons originate mainly from stars getting devoured by black holes and neutron stars.
As a black hole or neutron star destroys a star, tremendous amounts of radiation are released.
Just as electrons and positrons emit the tell-tale gamma rays upon annihilation, so too can gamma rays combine to form electrons and positrons, providing the mechanism for the creation of the antimatter cloud, scientists think.
