Fading Galactic Ghosts Discovered | Science News

Astronomers have uncovered a hidden population of young, fading “ghost galaxies” whose supermassive black holes have shut down their powerful radio jets—revealing a cosmic puzzle piece missing for decades. Using global radio telescopes, researchers confirmed twelve of fourteen candidates are indeed these rapidly dimming remnants, some as young as billions of years old and located light-years away. The study shows particles in their lobes still evolve even after jet shutdown, shaped by cosmic background radiation and magnetic fields. This discovery reshapes our understanding of how often black holes switch on and off—and with next-gen telescopes like the Square Kilometre Array, scientists expect to uncover thousands more of these cosmic ghosts.
