Beauty

Not a tattoo on human skin.

Not a design on cloth.

Not a work of art.

It's sand dunes on Mars. Sand dunes, dust, swirling dust devils. Go to Bad Astronomy for a more complete explanation of what's what; it's where I stole the picture from.

The picture was taken by the Mars Reconnaissance Orbiter.

I'd say more, but am frankly left rather speechless. Just gorgeous.
