ALT An astronaut aboard the International Space Station took this photograph of small island cays in the Bahamas and the prominent tidal channels cutting between them. For astronauts, this is one of the most recognizable points on the planet. The string of cays — stretching 14.24 kilometers (8.9 miles) in this image — extends west from Great Exuma Island (just outside the image to the right).
ALT NASA astronaut Kjell Lindgren took this photograph on Nov. 11, 2015 from the International Space Station, and shared it with his followers on social media. Lindgren wrote, "The delicate fingerprints of water imprinted on the sand. The #StoryOfWater." The area photographed is located in Oman, approximately 20 km to the west-northwest of Hamra Al Drooa.
ALT Since 1953, many successful expeditions have climbed Mt. Everest, including the first American expedition in 1963. However, most climbers fail to make the peak, and many people die each year in the attempt. As of 2003 when this Landsat 7 image was taken, more than 5,000 people have attempted to repeat their feat with only 1,600 successes and 175 fatalities.
