A NASA aircraft has spotted something in the Arctic that it can't explain and it has "never seen before."
On April 14, NASA's Operation Ice Bridge captured images over the Beaufort Sea, 50 miles northwest of the Mackenzie River Delta. The images, taken by mission scientist John Sonntag, show unusual or "curious" circles that the government agency can't explain.
