#geyser
Colourful auroras erupted unexpectedly a few years ago, with green aurora appearing near the horizon and brilliant bands of red aurora high overhead. The Moon lit the foreground of this scene, while familiar stars could be seen in the distance. The astrophotographer shot this image mosaic in the field of White Dome Geyser in Yellowstone National Park in the western USA. Sure enough, just after midnight, the geyser erupted – spraying a stream of water and vapor many meters into the air. Geyser water is heated to steam by scalding magma several kilometers below, and rises through rock cracks to the surface. About half of all known geysers occur in Yellowstone National Park.
