Three panels, each showing an alternative view of the first quasar, 3C 273. The rightmost panel shows a white, star-like image from the Hubble Space telescope, with a scale of 86,000 light-years. The middle panel shows a zoomed-in view from the High Sensitivity array, at a scale of 40 light-years. The bright source of the quasar is orange, and a blue and pink jet extends rightward out of the source. The leftmost panel shows the quasar as seen by the Global Millimeter VLBI Array and ALMA. The source is greatly magnified to show additional detail of the quasar and its extended blue and pink plasma jet to the right.
