  1. This project has received funding from the European Union’s Seventh

    Framework Programme for research, technological development and demonstration under grant agreement № 606874. This image displays all 867 DustPedia galaxies; every galaxy within 140 million light-years of us (that has an angular size over 1/60th a degree) that was observed by the Herschel Space Observatory. In each RGB image, red is far-infrared Herschel data showing emission from cold interstellar dust, green is near-infrared SDSS data showing light from populations of older stars, and blue is ultraviolet GALEX data showing emission from newborn stars. Each image is scaled to the optical size of galaxy (down to a minimum of 1/30th a degree). Images with ‘speckled’ red data are where foreground dust or background galaxies outshine the target galaxy.
