Sandstorms, like this one pictured blowing sand and dust across the Mediterranean Sea from the Libyan Desert on February 10, 2007, are usually the result of atmospheric convection currents, which form when warm, lighter air rises and cold, heavier air sinks. The cold air in this image is visible stretching from the top left side of the image down to the center and swirling back towards the north just above Libya, while the warm air current is seen blowing sand from south to north.

Cleveland Volcano, situated on the western half of Chuginadak Island, produces a plume of ash at 3:00 p.m. Alaska Daylight Time on May 23, 2006. Cleveland Volcano is one of the most active of the volcanoes in the Aleutian Islands. Flight Engineer Jeff Williams, from International Space Station (ISS) Expedition 13, took this photograph shortly after its activity began. Two hours later, the plume had completely detached from the volcano and the Alaska Volcano Observatory reported that the ash cloud height could have been as high as 6,000 meters (20,000 feet) above sea level.

This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd martian day, or sol, of its mission. The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see. The inset shows a combination of four panoramic camera images zoomed in on Earth. The arrow points to Earth. Earth was too faint to be detected in images taken with the panoramic camera's color filters. (UPI Photo/NASA/JPL/Cornell/Texas A&M) | License Photo

NASA's Mars Phoenix Lander can be seen parachuting down to Mars, in this image captured by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. This is the first time that a spacecraft has imaged the final descent of another spacecraft onto a planetary body. Phoenix released its parachute at an altitude of about 12.6 kilometers (7.8 miles) and a velocity of 1.7 times the speed of sound. The HiRISE acquired this image on May 25, 2008, at 4:36 p.m. Pacific Time (7:36 p.m. Eastern Time). (UPI Photo/NASA/JPL-Caltech/University of Arizona) | License Photo
