TL;DR Summary

Three galaxies observed during the Cosmic Dawn may be powered by dark matter collisions instead of nuclear fusion, according to astrophysicists using data from the James Webb Space Telescope. These dark stars could help explain the nature of dark matter and the abundance of supermassive black holes in the universe. Dark stars could address gaps in our understanding of dark matter, the first stars in the universe, and the rapid growth of galaxies since the Big Bang. While highly theoretical and requiring further observations, the researchers suggest that future telescopes could differentiate dark stars from early galaxies based on their helium signatures.
