(15 Oct. 2011) --- One of the Expedition 29 crew members aboard the International Space Station recorded this oblique view showing the Mediterranean Sea area, including the Nile River and the river's delta, and the Sinai Peninsula, on Oct. 15, 2011. Cyprus is visible at left. At first look, the image appears to have been photographed in daylight, but actually it was taken at 01:01:08 GMT. Some areas of the photo like the river and river delta appear as the brightest areas because of either man-made lighting (mostly incandescent) or man-made lighting reflected off nearby surfaces. The other areas appear to be illuminated naturally by moonlight, starlight, or back-scattered light from the atmosphere. A 20-mm focal length was used to record the image.
