Spectacular layers of Earth's atmosphere

By

Space.com highlights an image of the Earth's atmosphere, with its various distinct layers, as taken by astronauts onboard the International Space Station while passing over the Indian Ocean at sunset.


The June 14, 2010 Space.com article Earth's Colorful Atmospheric Layers Photographed from Space states, 'A brilliant sequence of colors in the image denotes each of the layers of Earth's atmosphere, which are visible here because the picture was taken while the space station had an edge-on, or limb, view of the Earth. From this vantage point, the Earth's curvature can also be made out.'

The article also states 'The astronaut aboard the space station was facing west when they snapped this picture. Astronauts in low-Earth orbit see 16 sunrises and sunsets every day due to their high orbital velocity (more than 17,000 mph, or 28,000 kph).'

The image of the atmosphere of Earth is found here.

The caption of the Space.com image states, 'This spectacular image of sunset on the Indian Ocean was taken by astronauts aboard the International Space Station (ISS).'

And, 'The image presents an edge-on, or limb view, of the Earth's atmosphere as seen from orbit. Credit: NASA."
