(Bonus: 1 of 3) This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth, released on March 22, 2012. Expedition 31 Flight Engineer (and photographer) Don Pettit: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 46 images photographed by the astronaut-monitored stationary camera in the Cupola were combined to create this composite. #
