Quizplus · Accepted Answer

Quasars are highly luminous objects that were first identified as being star-like in appearance but emit strong radio waves. However, not all quasars are radio-loud; some are radio-quiet, yet they share the same basic characteristics, including being extremely distant and bright, often outshining entire galaxies. They are powered by supermassive black holes at the centers of galaxies, making them some of the most luminous objects in the universe.
