The International Space Station Expedition 23 crew sent this photo to Earth taken of the Aurora Australis or "Southern Lights" from orbit. The limb of the Earth and some stars in the background are seen from nearly 200-miles above the planet.The aurorae are usually between 50-to–100 miles above the Earth’s surface. This particular May 29, 2010 sight was probably caused by subatomic particles from an explosive event called a coronal mass ejection from the Sun. Previous ISS shots of the Aurora Borealis have been a delight.
