On Art of Science, visitors can browse through seven online galleries of gorgeous, curious images. These images, as the website explains, "are not art for art's sake. Rather, they are produced during the course of scientific research." Since 2005, Princeton University has hosted seven contests that invite scientists around the world to submit photographs (and, during its most recent 2014 contest, videos) of images created from their work in science - including chemistry, biology, and computer science. These images are then judged "for their aesthetic excellence as well as scientific or technical interest." On this website, visitors can browse galleries of winning photographs, which include a model of earth's geomagnetic reversal, maps of website addresses and traffic, and the spectacular results of chemical reactions. All entries, with the exception of entries from the 2014 contest, are accompanied by a description explaining the image's origin and scientific significance.
