A satellite image from NASA captured an ominous-looking Hurricane Isaac as it approached the Gulf Coast.

According to NASA, the image was captured using the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths. In this case, the clouds of Isaac were lit by moonlight, and the lights from the cities sparkled like diamonds.
