Astronomers have found two close pairs of quasars in the distant Universe. Follow-up observations with Gemini North spectroscopically resolved one of the distant quasar pairs, after their discovery with the Hubble Space Telescope and Gaia spacecraft. These quasars are closer together than any pair of quasars found so far away, providing strong evidence for the existence of supermassive black hole pairs as well as crucial insight into galaxy mergers in the early Universe.
