Euclid is only 1.5 years into its Euclid Wide Survey and has found 31 new quasars from the Universe’s first 800 million years. Though the Survey isn’t specifically aimed at finding ancient quasars, it’s proving to be remarkably effective at it. This large sample of quasars will help with the study of ancient galaxies and supermassive black holes.
