Image of the Day: Algerian Abstract is a Work of Space Art

What seems to be yellow paint streaks slicing through a collection of colors are actually the ridges of wind-blown sand that make up Erg Iguidi, one of the Saharan sand seas. The image was captured from Landsat 7, an Earth-observing satellite managed by NASA and the U.S. Geological Survey (USGS). Erg Iguidi is an area of constantly shifting sand dunes that extend from Algeria into northwestern Africa. The Interior Department's Anne Castle, assistant secretary for water and science said, “Landsat has been a game changer for agricultural monitoring, climate change research and water management.”
