The supermassive black hole in the core of supergiantelliptical galaxy Messier 87, with a mass ~7 billion times the Sun's,[1] as depicted in the first image released by the Event Horizon Telescope (10 April 2019).[2][3][4] Visible are the crescent-shaped emission ring and central shadow, which are gravitationally magnified views of the black hole's photon ring and the photon capture zone of its event horizon. The crescent shape arises from the black hole's rotation; the shadow is about 2.6 times the diameter of the event horizon.[3]
