COVER In Science's 2019 Breakthrough of the Year, the Event Horizon Telescope (EHT) imaged superheated matter ringing the supermassive black hole in the galaxy M87. Here it is seen, outlined by the glowing ring, from an imaginary nearby planet. Hot gas and radiation jet from its pole, and its titanic gravity stretches background stars into so-called Einstein rings. Dimitrios Psaltis, EHT project scientist, advised on the illustration. See page 1434. For more on how the cover image was created, see
