There might be clusters of antimatter stars residing in our galaxy, producing a large amount of the high-energy antimatter that we have detected in space.
Let’s talk about antimatter for a bit, as it remains a mysterious subject for most people.
Antimatter is like the alter ego of matter. It is exactly the same as its matter counterpart, except for having the opposite sign of charge. And like any dramatic alter ego, the matter-antimatter combination leads to the annihilation of both, releasing a massive amount of energy.
Another exciting explanation comes in the form of supernovae. These are exploding stars that have reached the end of their lifetime. In this case, the explosions would be of antimatter stars. Antihelium present deep inside the stars is purged out into the interstellar medium when the star explodes. The energy of the explosion is so high that the antimatter would have enough to overcome the magnetic barrier of the galactic disk and reach the Solar system.
Conclusion
So how do we know if this theory is possible? For confirmation, scientists performed simulations and concluded that there really might be globular clusters of antimatter stars hanging out in our Milky Way galaxy. It’s insane to think such things exist, but now that we have detected the emissions from these antimatter stars, researchers are eager to detect the stars themselves. Considering the way this theory is garnering more and more attention, there will be telescopes looking out for them soon enough!
