Galaxy Zoo 2 images
An international group of researchers, led by the University of Minnesota, has produced a catalog of data for more than 300,000 galaxies. More than 83,000 volunteer citizen scientists contributed to the crowdsourcing project called Galaxy Zoo 2. The effort resulted in more than 16 million galaxy classifications.
