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.
