Artist’s impression of ALMA observations of a gravitationally-lensed supermassive black hole

This artist’s representation shows the gravitationally-lensed black hole PKS1830-211 and the sudden flaring seen with ALMA when material enters the base of the jet, close to the black hole itself. Orange indicates the jet seen in radio waves; green, blue, and red are the (changing) images seen with ALMA and the white flashes represent gamma rays.
