Quasars are among the most energetic and luminous objects in the universe, formed by the intense accretion of matter onto supermassive black holes at the centers of galaxies. These distant celestial objects have been fascinating astronomers and cosmologists for decades, providing crucial insight into the early universe and the evolution of galaxies. In this quiz, you'll get to test your knowledge of quasars and learn more about their properties, behavior, and impact on our understanding of the universe. From the brightest quasars to the farthest, this quiz will cover it all. So come along, and explore the brilliant world of quasars!
