The first photographs of a new and ominous crack in Greenland's enormous Petermann Glacier were captured by a NASA airborne mission Friday. NASA's Operation IceBridge, which has been flying over northwest Greenland for the past several days, took the photos after being provided coordinates by Stef Lhermitte, a professor at Delft University of Technology in the Netherlands, who had spotted the oddly located chasm by examining satellite images.
