3400 x 2800 20 MB - GeoTIFF
Published March 30, 2008
Spider Crater rests in a depression some 13 by 11 kilometers (8 by 7 miles) across. Meteorite craters often have central areas of uplift, and Spider Crater fits this pattern. Spider Crater sits in a depression and has a central uplift area characteristic of impact craters, it shows extreme differences in erosion, giving it a unique appearance.

Lake Naivasha, Kenya
Published March 26, 2008
A quarter of the cut flowers sold in Europe are grown in Kenya. Straddling the equator, Kenya gets steady sunlight dealt out in days that vary little in length. It’s the perfect climate for flowers year-round. The center of Kenya’s flower industry is Lake Naivasha.

Serra da Cangalha Crater, Brazil
Published March 16, 2008
Roughly 220 million years ago, geologists estimate, a meteorite struck Earth here. Despite its age, Serra da Cangalha remains Brazil’s best-preserved impact crater, resting upon largely undisturbed sediments laid down some 300 million years ago.

Chorabari Glacier, India
Published March 14, 2008
Because Indian glaciers have not been studied in detail for the past several decades, assessing their long-term trends has been difficult. More recent studies, however, suggest they are vulnerable to rising temperatures, which increased by 2.2 degrees Celsius (3.96 degrees Fahrenheit) between the 1980s and the new millennium.

Ries Crater, Germany

Published March 9, 2008
Germany’s Ries Crater (or Nördlinger Ries) is not easily discerned in space-based images. The crater’s existence was probably just as subtle to the medieval Europeans who established a settlement inside it and unknowingly matched their 1-kilometer- (0.6-mile-) wide city to the likely diameter of the meteorite that formed the crater.
