Quasars are incredibly disson in energetic celestial objects. They are powered by supermassive black holes at their centers. These black holes consume vast amounts of matter, releasing enormous amounts of energy in the process. Quasars emit intense radiation across the electromagnetic spectrum, making them some of the brightest objects in the universe. Their immense luminosity allows astronomers to study the early universe and gain insights into the formation and evolution of galaxies. Quasars are fascinating and important objects in our understanding of the cosmos.
