An extremely luminous active galactic nucleus powered by a supermassive black hole, visible across billions of light-years.
From 'quasi-stellar radio source,' coined in the 1960s. The brightest objects in the universe — a single quasar can outshine its entire galaxy of hundreds of billions of stars.
A black hole eating SO much material it becomes the BRIGHTEST thing in the universe! One quasar outshines a TRILLION suns! The name is short for 'quasi-stellar' because astronomers first thought they were weird stars. NOPE — cosmic monsters! 🕳ï¸âœ¨
