Supermassive Black Holes Can Render Exoplanets Uninhabitable at Great Distances

Life on Earth relies on energy from astrophysical sources. But what if the astrophysical source isn't a star, but a supermassive black hole and its active galactic nuclei? Life needs shelter from their powerful energy, and the only shelter is distance. New research shows that SMBH and their AGN could strip away exoplanet atmospheres and destroy their ozone at vast distances.
