Richat Structure

Here is a satellite image of the so-called Richat Structure, a geological formation in the Maur Adrar desert, in Africa's Western Sahara. The structure formed when a volcanic dome hardened and then gradually peeled away to show the layers of the rock.

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.

Flower

This developing flower displays the spiral form in two aspects: The whole flower begins in a spiral and unfolds as it opens, while the tips of the petals form tiny inward spirals.

Nautilus shell

The nautilus is a cephalopod, like the octopus and squid. Unlike some animals in this class, it has a hard outer shell, which is divided into chambers. As the nautilus grows in size, it periodically seals off the shell behind it and creates a new, larger chamber to live in. This ongoing process creates the familiar spiral structure that is visible when a nautilus shell is sliced in half.
