We don’t see analogs of them at lower redshifts, which is why we haven’t seen them prior to Webb,” Dale Kocevski of Colby College in Waterville, who led the study, said in a Space Telescope ...

Due to their exceptional brightness, these objects can be seen at high redshifts, i.e., large distances. A higher redshift not only indicates a quasar is at a greater distance but also further ...
