Looking at photographs of galaxies, one gets the impression that they are gas clouds, as they were actually considered before the resolution of optical instruments allowed us to identify individual sources. As in these splendid images from HST (the Hubble Space Telescope) and VISTA (the Visible and Infrared Survey Telescope for Astronomy, part of ESO’s Paranal Observatory).
