Scientists have been talking of antimatter for a long time. All elementary particles, such as protons and electrons, have antimatter counterparts with the same mass but the opposite charge. For instance, the antimatter opposite of an electron, known as a positron, is positively charged. When Antimatter comes in contact with matter, it annihilates it. The source of this anti-matter was always a quirky question for the scientists. Now they have an answer:
The researchers calculate that a relatively ordinary star getting torn apart by a black hole or neutron star orbiting around it — a so-called “low mass X-ray binary” — could spew on the order of one hundred thousand billion billion billion billion positrons (a 1 followed by 41 zeroes) per second. These could account for a great deal of the antimatter that scientists have inferred, reducing or potentially eliminating the need for exotic explanations such as ones involving dark matter.
