Green Aurora Iss
This snaking green aurora was the result of a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun on May 24, 2010.
Astronauts aboard the International Space Station captured this picture of the light show as they orbited over the Southern Indian Ocean at an altitude of 220 miles (350 kilometers), with the astronaut observer most likely looking towards Antarctica (not visible) and the South Pole.
The aurora has a sinuous ribbon shape that separates into discrete spots near the lower right corner of the image. While the dominant coloration of the aurora is green, the most commonly observed aurora color, there are faint suggestions of red left of image center.
