On April 20, 2010, an explosion on the Deepwater Horizon oil platform in the Gulf of Mexico killed eleven workers, sunk the platform, and left its seafloor well gushing. This initiated a massive offshore oil spill—the largest in U.S. history. The spill continued until July 15, 2010, causing immense surface oil slicks and ecological damage to the U.S. coastline. In this false-color Landsat 7 image, a colossal oil slick can be seen floating southeast of the Mississippi Delta.
