Starry Night Scavenger Hunt
Image Credit: Vincent van Gogh; Digital Collage & Copyright: Ronnie Warner

Explanation: Did you know that van Gogh's painting Starry Night includes Comet Hale-Bopp? Hopefully not, because it doesn't. But the featured image does. Although today's picture may appear at first glance to be a faithful digital reproduction of the original Starry Night, actually it is a modern rendition meant not only to honor one of the most famous paintings of the second millennium, but to act as a scavenger hunt. Can you find, in the featured image, a comet, a spiral galaxy, an open star cluster, and a supernova remnant? Too easy? OK, then find, the rings of Supernova 1987A, the Eskimo Nebula, the Crab Nebula, Thor's Helmet, the Cartwheel Galaxy, and the Ant Nebula. Still too easy? Then please identify any more hidden images not mentioned here -- and there are several -- on APOD's main discussion board: The Asterisk. Finally, the collagist has graciously hidden APOD's 10th anniversary Vermeer photomontage just to honor APOD. (Thanks!)
