A crew member floating inside the International Space Station snapped this long-exposure photo of the southern lights dancing through Earth’s atmosphere on July 16.Such light shows occur when high-energy solar particles corralled by Earth’s magnetic field slam into atmospheric gas near the planet’s poles (in this case, somewhere over Antarctica).
At left is part of the space station’s solar arrays, and at center is space shuttle Atlantis’ robotic arm and inspection boom, which is backlit by the moon. One of Atlantis‘ wings, orbital maneuvering system pods and payload bay doors is seen at right. (source)
