Washington, April 17: NASA on Friday clicked photographs of a new crack in one of the Greenland's largest Petermann glacier, during Operation IceBridge.

NASA's airborne mission has been fluying over northwest Greenland for the past several days.

Here are some pics that were shared by NASA on the social networking site Facebook. Let's take a look:

Portion of the new rift on Petermann Glacier's floating ice shelf (straight feature near bottom center), and an older curved rift from the flank of the shelf near top center. The shaded feature near bottom center is a medial flowline, whose presence may exert a stagnating effect on the propagation of the new rift toward the older one. [Pic Credit: NASA/Kelly Brunt]
