If starry galaxies are like bright ships on a cosmic sea, then supermassive black holes are like their dark anchors. In a new study, astrophysicists report the best-yet example of a supermassive black hole far from its galactic center. Published in Astrophysical Journal Letters, the result reveals the presence of a million-solar-mass black hole. Using all-too-brief TDEs to spot wandering black holes can make in-depth follow-up research difficult, according to Pieter van Dokkum, an astrophysicist at Yale University. “Understanding where this supermassive black hole came from is quite interesting,” Islam says.
