Composite False-Color Image of the Quasar Jet 3C273

Caption: Composite false-color image of the quasar jet 3C273, with emission from radio waves to X-rays extending over more than 100,000 light years. The black hole itself is to the left of the image. Colors indicate the wavelength region where energetic particles give off most of their energy: yellow contours show the radio emission, with denser contours for brighter emission (data from VLA); blue is for X-rays (Chandra); green for optical light (Hubble); and red is for infrared emission (Spitzer).

The jet suddenly becomes very bright at A, where the high-energy X-ray emissions dominate; moving further away from the quasar, progressively lower-energy emissions dominate. Letters label individual jet features.
