DISCOVERY OF GIANT RADIO GALAXIES AND SUPERMASSIVE BLACK HOLES Colleague Dr. Sabayashi Pal. Astronomers have discovered 53 giant radio galaxies, some 75 times larger than the Milky Way, powered by active supermassive black holes emitting radio jets. These ancient objects offer insights into galactic evolution, contrasting sharply with the Milky Way's smaller, dormant black hole that allows life to exist safely. NUMBER 13
