Supermassive Black-Hole Eruptions Occur About Every 10,000 Years 


NASA Black Hole Eruption


A star that wanders too close to the supermassive black hole in the center of its galaxy will be torn apart by the black hole’s gravity in a violent cataclysm called a tidal disruption event (TDE), producing a bright flare of radiation. A 2018 study led by theoretical astrophysicists at the University of Copenhagen’s Niels Bohr Institute and UC Santa Cruz provides a unified model that explains recent observations of these extreme events.
