Created by Buddy Valastro of Carlo's Bakery ("Cake Boss"), the cake's engines amazingly fired, and the cake rose a few inches into the air.

Not a single photograph, the image combines 1,700 images collected over 6 lunar days (6 Earth months) into a multi-temporal illumination map. Analyzing the digitized images, each pixel in the map represents the percentage of time each spot on the moon's surface was illuminated by the sun. Since the moon's spin axis remains almost perpindicular to the ecliptic plane, some areas near the lunar poles can stay in permanent darkness or nearly continuous sunlight. The Shackleton Crater lies at near the center of the map.
