Astronomers capture the highest resolution images ever taken of a black hole
Active galactic nuclei (AGN) are among the most energetic phenomena observed in the universe. These luminous objects, powered by supermassive black holes at the centers of galaxies, release staggering amounts of energy as matter spirals into their intense gravitational pull.
Astronomers capture unprecedented view of supermassive black hole in action
Active galactic nuclei are supermassive black holes at the center of certain galaxies. As matter falls into these black holes, enormous amounts of energy are released, making active galactic nuclei, or AGN,
