Image of the Day: A Crack Across the Pine Island Glacier

A massive crack extending for 19 miles across the Pine Island Glacier in Antarctica was discovered last October by NASA scientists working in the area. The crack is 260 feet wide, 195 feet deep and will eventually extend all the way across the glacier, calving a giant iceberg that will cover about 350 square miles. This image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft on Nov. 13, 2011.
