Here’s a gallery with more horrifying photos, including this one from NASA.

Handout photo from NASA made available 27 April 2010 showing the oil spill from the Transocean Deepwater Horizon drill rig disaster located in the Gulf of Mexico off Louisiana, USA on 25 April 2010. This NASA/ALI image taken from the EO-1 satellite shows some of the oil slicks and sheen (bright areas). The spill source is a leaking well on the seafloor located near bottom center of this image. An estimated 42,000 gallons (160,000 liters) of oil per day are leaking from the damaged oil well. EPA/NASA HANDOUT (via)
