Jet and shadow of the black hole at the center

    This image shows the jet and shadow of the black hole at the center of the M87 galaxy together for the first time. The observations were obtained with telescopes from the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA), of which the European Southern Observatory is a partner, and the Greenland Telescope. This image gives scientists the context needed to understand how the powerful jet is formed. R.-S. Lu (SHAO), E. Ros (MPIfR), S. Dagnello (NRAO/AUI/NSF/Handout via REUTERS
