Centaurus A – Field 2 (halo)

Colour composites of "Field 2" in the halo of the peculiar galaxy Centaurus A (NGC 5128), based on exposures through three near-infrared filters (the J-, H- and K-bands at wavelengths 1.2, 1.6 and 2.2 µm, respectively) with the ISAAC multi-mode instrument at the 8.2-m VLT ANTU telescope at the ESO Paranal observatory. This ISAAC image is one of the two deepest near-infrared images ever obtained in this galaxy and shows thousands of its stars of different colours. In the present colour-coding, the redder an image, the cooler is the star. The original pixel size is 0.15 arcsec and both fields measure 2.5 x 2.5 arcmin 2. North is up and East is left.
