While antistars are highly speculative, if they are real, then they may be revealed by their production of weak gamma-ray emission peaking at 70 MeV, when particles of normal matter from the interstellar medium fall onto them and are annihilated.Īntihelium-4 was created for the first time in 2011, in particle collisions at the Relativistic Heavy Ion Collider at the Brookhaven National Laboratory.
ANTIMATTER STAR ARCHIVE
Three astronomers at the University of Toulouse – Simon Dupourqué, Luigi Tibaldo and Peter von Ballmoos – found the possible antistars in archive gamma-ray data from NASA’s Fermi Gamma-ray Space Telescope. (Courtesy: Simon Dupourqué/IRAP)įourteen possible antimatter stars (“antistars”) have been flagged up by astronomers searching for the origin of puzzling amounts of antihelium nuclei detected coming from deep space by the Alpha Magnetic Spectrometer ( AMS-02) on the International Space Station. After eliminating known objects and sources that lacked the spectral signature of an antistar, 14 possibles remained.
