"Cloud Streets Across Caspian Sea": one of many images available at NASA's Earth Observatory.
The accompanying photo gallery is a just small taste of the hundreds of images available. The Earth Observatory online library stretches back to 1999, providing a graphic snapshot of how nature and man create changes on the surface of the planet.
In February, dust storms can be seen curling off the coast of Morocco, carrying plumes of sand out across the Atlantic Ocean. NASA suggest that these storms could be the result of stresses on the land surface -- such as overgrazing and damage to vegetation -- caused by humans.
A satellite image taken in March shows a section of the Wilkins Ice Shelf in Antarctica, measuring 41 kilometers by 2.5 kilometers, crumble away into the sea. And the image of Tokyo at night looks like a giant electrical circuit board -- which, of course, it is.
Meanwhile, south of Sudan's capital, Khartoum, the geometric shape of irrigated fields reveal a man-made collage of rivers and crops while the swollen waters of the Mississippi break the levees in Gulfport, Illinois in June 2008, leaving homes submerged and lives in ruin.

Two hundreds miles above Central Asia, the skies are visibly calmer as polar mesospheric clouds are captured on film. While the earth is still shrouded in darkness, the clouds are illuminated by the first streaks of sunlight. NASA says that polar mesospheric clouds are not uncommon over Northern Asia. Some researchers link increased observations of them to climate change.
A picture taken by an astronaut shows the Amazon burnished in gold as the light of a setting sun transforms the appearance of the river and its tributaries in Brazil. While the iridescent waters off the coast of Texas and Louisiana reveal the environmental jolt of a storm surge created by Hurricane Ike.
A contrasting aftermath of nature's force can be seen in the image of the charred peaks of the Chino Hills in southern California which show the extent of damage caused by the recent fires. iReport.com: Are you a stargazer? Share your images
