False-colour CCD-image of the southern radio galaxy PKS 2152-69
This false-colour CCD-image of the southern radio galaxy PKS 2152-69 shows the gas cloud in which quasar-like activity has been discovered. The highly energetic cloud is seen to the upper left of the bright centre in the otherwise normal radio galaxy. The image was obtained by subtracting a continuum image from another made in the red light of hydrogen and nitrogen. They were exposed with a CCD camera at the 2.2 m telescope at the ESO La Silla observatory.
