Quasars News
Quasars, or quasi-stellar objects, are extraordinarily bright astronomical objects located at the centers of distant galaxies, powered by supermassive black holes. As material falls into these black holes, it heats up to extreme temperatures, causing quasars to emit incredible amounts of energy, including visible light, radio waves, and X-rays. They are among the most luminous, powerful, and energetic objects in the universe, often outshining the entire galaxies in which they reside. Quasars were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, during the 1960s. Their discovery was significant because it provided a profound glimpse into the processes occurring in the early universe. The study of quasars and other active galactic nuclei (AGN) is crucial for understanding the formation and growth of galaxies, the behavior of matter under extreme gravity, and the history of the universe itself.
