Black Hole Radiation Could Aid Life on Distant Planets, Study Suggests

Research indicates that under specific conditions, radiation emitted by black holes could foster life on planets. Supermassive black holes at the center of galaxies emit high-energy radiation as they consume matter. A study in The Astrophysical Journal suggests this radiation, paradoxically, might benefit life. Modeling shows ultraviolet radiation from black holes could alter planetary atmospheres, either halting life's development or helping it thrive. The impact depends on a planet's proximity to the black hole and the presence of primitive life forms. For instance, early Earth saw increased ozone due to microbes releasing oxygen, shielding the planet from harmful radiation. Planets farther from a galaxy's center experience less black hole radiation. The distance of a planet from a black hole and the presence of oxygen are key factors in determining whether radiation hinders or promotes life. Black hole radiation could potentially support complex life on habitable planets.
