This other worldly image is not other worldly at all, it's from our
own Earth. This true color image is from space looking down at an
area just off shore of an island in the Bahamas. The patterns
result from four factors; a strong Gulf Stream current, wave
action, sand, sea weeds and other aquatic plants.

In this Advanced Spaceborne Thermal Emission and Reflection
Radiometer (ASTER) image the features that look like folded
material are calcium carbonate (a mineral composed of calcium,
carbon, and oxygen) sand dunes in the shallow waters of
Tarpum Bay, southwest of Eleuthera Island in the Bahamas.
The sand making up the dunes comes from the erosion of
limestone coral reefs, and has been shaped into dunes by
ocean currents. The image was acquired on May 12, 2002
and the image covers an area of 28.2 x 46.1 km.

Where the Volga River flows into the Caspian Sea, it creates an
extensive delta. The Volga Delta is comprised of more than
500 channels and sustains the most productive fishing grounds
in Eurasia. Image courtesy of NASA.

Hemmed in by levees the Mississippi River delta is
slowly vanishing. Image courtesy of NASA.

San Francisco bay tidal drainage. The red - pink patchwork
pattern seen at the southern end of the bay is a cluster of
commercial salt evaporation pools. The unusual color is
caused by halophiles, a group of salt loving bacteria.
