Quasar 3C 273 observed by the Hubble Space Telescope. The relativistic jet of 3C 273 appears to the left of the bright quasar, and the four straight lines pointing outward from the central source are diffraction spikes caused by the telescope optics.
UGC 6093 is classified as an active galaxy, which means that it hosts an active galactic nucleus.
