This image, taken by NASA’s James Webb Space Telescope, shows an ancient quasar (circled in red) with fewer than expected neighboring galaxies (bright blobs), challenging physicists’ understanding of ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...
