This unusual photo of the Arnica Fire in Yellowstone National Park was taken by astronauts aboard the International Space Station.
Here's how the folks at NASA's Earth Observatory described the shot:
The late summer/fall wildfire season is in full swing in the western United States. Significant wildfires are observed each year by astronauts orbiting the Earth on the International Space Station. This astronaut photograph documents the Arnica Fire in Yellowstone National Park. The fire was started by a lightning strike near Yellowstone Lake on September 13, 2009. By the time it was detected on September 23, 2009, it covered approximately 2 hectares (4 acres). The fire was photographed by the astronauts on the following day (September 24); by then, it had grown to 101 hectares (250 acres) in size. Warm, dry and windy conditions in the area provided a favorable environment for growth of the fire, and as of October 1, 2009, the fire was estimated to be 3,764 hectares (9,300 acres) in size.
The image is highly oblique, or taken looking outwards at an angle, rather than straight down towards the Earth’s surface. The ISS was approximately above Lake Winnipeg, Manitoba, Canada—almost 1,200 kilometers (746 miles) to the northeast of the fire—when this image was taken using a long lens. Landmarks visible in the image include Yellowstone and Jackson Lakes at image center; the Teton Range is visible in the background. The reflection of the smoke plume is visible in Yellowstone Lake.

WOW My girlfriend and I entered Yellowstone on Sept. 15, and hiked the Natural Bridge trail on the 21st. I'm having a hard time understanding how a fire that turned so big could have been 8 days old already during our hike. We left the Teton area the morning after this pic was taken. We could see the smoke from the Bearpaw fire from our cabin at Signal Mountain, but never any smoke from the Arnica fire. We consider ourselfs very lucky that this didn't cause us to have to change any of our plans.
