The elliptical galaxy M87 sits 55 million light-years away, at the heart of the nearby Virgo Cluster. Deep inside this galaxy lurks a supermassive black hole that weighs 6.5 billion times the mass of our Sun. That black hole instantly became famous in 2019 when the Event Horizon Telescope (EHT) collaboration released its portrait — the first ever direct image of the shadow of a black hole.
