Triple Black Hole Feast: Astronomers Catch Three Hungry Monsters in a Cosmic Collision! For the first time ever, scientists have confirmed a wild triple galaxy merger where all three galaxies host actively feeding, radio-bright supermassive black holes—long predicted, but never seen until now.Located 1.2 billion light-years away in the system J1218/1219+1035, these three interacting galaxies are lighting up the radio sky as their central beasts devour gas and launch powerful jets. High-resolution observations from the VLA and VLBA revealed compact radio cores in each nucleus, proving this is the universe's first confirmed "triple radio AGN."This rare cosmic laboratory reveals how extreme mergers fuel black hole growth, drive galaxy evolution, and set the stage for future gravitational wave-ripping black hole collisions.
