Today’s Image of the Day comes thanks to the NASA Earth Observatory and features a look at Isla Mayor, a small island in the delta of the Guadalquivir River.

Isla Mayor is located in southwestern Spain and contains Doñana National Park, which is a marshland recently named an official UNESCO World Heritage Site.

The brightly colored squares in the center of the image are fish ponds and the darker rectangles are rice fields. Sea bass, shrimp, grey mullet, and meagre are all farmed here.

This image was taken by an astronaut on board the International Space Station.
