James Webb Space Telescope Identifies Potential Supermassive Dark Stars in Early Universe
Recent observations from the James Webb Space Telescope (JWST) suggest the existence of supermassive dark stars, massive hydrogen-helium clouds powered by dark matter annihilation, in the early universe. A study led by Cosmin Ilie of Colgate University, with researchers from the University of Pennsy... [More info]
Les astrophysiciens relativistes se posent des questions au sujet de l'existence d'étoiles incroyablement massives depuis presque 60 ans car elles donnent des solutions à certaines énigmes. Elles auraient notamment fait partie des toutes premières étoiles nées après le Big Bang, mais aucun télescope n'en avait jusqu'ici découvert. Remarquablement, cela vient peut-être de changer...
Possible #firstevidence for #supermassivestars at the origin of #globularclusters
https://phys.org/news/2023-05-evidence-supermassive-stars-globular-clusters.html
Globular clusters are the most massive and oldest star clusters in the universe. They can contain up to 1 million stars. The chemical composition of these stars, born at the same time, shows anomalies that are not found in any other population of stars. Explaining this specificity is one of the great challenges of astronomy.
