In this June 18, 2010 satellite image provided by NASA, oil from the Deepwater Horizon rig is visible on the surface of the Gulf of Mexico. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture. The oil appears as varying shades of white, as sunlight is reflected off its surface.
