GREENApril 27 (UPI) -- Next time you're passing above North Africa at an altitude of 440 miles, check out the Haruj volcanic field in central Libya. From space, the volcanic plateau looks like a giant oil spill.
This week, NASA released a stunning image of the expansive Haruj. The image is the amalgamation of hundreds of photographs collected by NASA's Landsat 8 satellite and its Operational Land Imager between July 24, 2013 and April 13, 2016.
