Quasar 3C273

Quasar 3C273 observed by the Hubble Space Telescope (HST) (left). The exceeding brightness results in radial leaks of light created by light scattered by the telescope. At the lower right is a high-energy jet released by the gas around the central black hole. | Radio image of 3C273 observed by ALMA, showing the faint and extended radio emission (in blue-white color) around the nucleus (right). The bright central source has been subtracted from the image. The same jet as the image on the left can be seen in orange. Credit: Komugi et al., NASA/ESA Hubble Space Telescope
