Dark stars “would be the very first stars, before anything else, and they would be very weird looking.”
The James Webb Space Telescope has spotted objects in the early universe that might be a new kind of star — one powered by dark matter.
Dark stars “would be very weird looking,” says Freese, of the University of Texas at Austin. The hypothetical stars would have formed from clouds of hydrogen and helium that drew in locally abundant dark matter as they coalesced.
To see if any dark stars are lurking in data from the orbiting observatory, Freese and colleagues pored over images from a JWST survey of early galaxies. In such images, JWST has so far discovered over 700 objects that may have originated Those objects are currently thought to be small galaxies from the universe’s relative infancy. But because they’re so far away, JWST can’t resolve them well enough to determine whether they’re actually galaxies or large, ultrabright stars, the researchers say.
