kvázar
A quasar, short for quasi-stellar radio source, is an extremely luminous and distant active galactic nucleus. They are among the most energetic and distant objects known in the universe, and are believed to be powered by supermassive black holes at the centers of galaxies. Quasars emit enormous amounts of energy across the electromagnetic spectrum, from radio waves to X-rays, and are often referred to as the "lighthouses" of the universe due to their extreme brightness.
Quasars were first identified in the 1960s through their strong radio emissions. They are typically found at
The study of quasars has provided valuable insights into the early universe and the formation of galaxies.
Despite their brightness, quasars are not visible to the naked eye due to their immense distance. They
