NASA's Terra satellite captured a visible satellite image of the Gulf oil spill on May 17 at 16:40 UTC (12:40 p.m. EDT) from the Moderate Resolution Imaging Spectroradiometer Instrument on-board. The oil slick appears as a dull gray on the water's surface and stretches south from the Mississippi Delta with what looks like a tail. Text Credit: NASA Goddard / Rob Gutro
