Von Karman Vortices
A satellite image taken of cloud formations over Alaska's Aleutian Islands. Also called Von Karman Vortices, the formations are created when air flows over and around objects in their path to create spiraling eddies in the sky. These particular eddies formed when winds swept east across the northern Pacific Ocean, where they hit the Aleutian Islands.
