The photos were taken as part of Operation IceBridge, an ongoing NASA mission to document changes in polar ice. During a flight over the northern Antarctic Peninsula on October 16, scientists captured images of the rectangular iceberg while gathering information on changes in the ice heights of various glaciers in the area.
Senior support scientist Jeremy Harbeck noticed the iceberg just off the Larsen C ice shelf.
"I often see icebergs with relatively straight edges, but I've not really seem one before with two corners at such right angles like this one," Harbeck said in a NASA press release.
"I was actually more interested in capturing the Delaware-sized A68 iceberg next to it we were about to fly over but thought this one was visually interesting and fairly photogenic, so on a lark, I just took a couple photos."
Take a look at photos of the sharp-angled iceberg below.

On October 16, NASA scientists found a number of large icebergs between Antarctica's Larsen C ice shelf and the A-68 ice island, which separated from the ice shelf last year.
The A-68 ice island is roughly the size of Delaware.
NASA's flying research laboratory carried the scientists around Antarctica. The aircraft is a modified Douglas DC-8 jetliner.
Just past the now-famous iceberg, NASA also captured another iceberg that was relatively rectangular.
