Discovery of Potential Antimatter Stars: A New Perspective
Written on
Chapter 1: Introduction to Antimatter Stars
Recent findings published in Physical Review D indicate the intriguing possibility of antistars—stellar objects composed of antimatter. If validated, this research could reveal that significant quantities of antimatter exist in isolated regions of the cosmos.

The research team analyzed a decade's worth of data from the Fermi Gamma-Ray Space Telescope. Out of a total of 5,800 gamma-ray sources, they identified 14 with energies indicative of matter-antimatter annihilation. This annihilation occurs when a particle collides with its antiparticle, resulting in their mutual destruction. The observation of such collisions in space suggests the presence of antimatter in those regions.
Section 1.1: Evidence from Gamma-Ray Sources
The 14 gamma-ray sources identified in this study did not correlate with any known sources, including black holes or pulsars, which adds further weight to the antistar hypothesis. However, confirming these as genuine antistars remains a formidable challenge.
“It would be practically impossible to assert that [the candidates] are actually antistars. It would be much easier to disprove,” states Simon Dupourqué, co-author of the study and astrophysicist at the Institute of Research in Astrophysics and Planetology in Toulouse, France.
Subsection 1.1.1: Statistical Insights
According to the findings from this study, if antistars do exist, they may be found at a ratio of 1 for every 400,000 ordinary stars within the Milky Way's plane, where the gamma-ray sources were detected. Outside of this plane, the ratio could rise to 1 antistar for every 10 ordinary stars. However, additional research is required to identify more gamma-ray sources that could potentially be classified as antistars.
Section 1.2: Implications for Cosmology
If antistars are indeed present, they would not be numerous enough to explain the entirety of the missing antimatter in the universe. Ongoing research aims to uncover this elusive mass, and studies like this one may eventually illuminate the mystery.
