Their observations suggest that even faint black holes are not simple bottomless pits. A Black Hole Eruption Observed in DetailUsing the European Southern Observatory’s Very Large Telescope (VLT), researchers tracked the newly discovered black hole system Swift J1727.8−1613 during a major eruption in 2023. Watching a Black Hole Change Over TimeThe research produced one of the most detailed optical records of a black hole eruption to date. This means black holes may continue producing strong outflows long after their brightest and most dramatic phase has passed. Black Holes May Be Inefficient EatersThe observations strengthen growing evidence that black holes are not simply cosmic consumers.
