It's been a while. Cool shot from space.
Bathed in the lights of the night
At night the skies glow with manmade lights, and above these are the lights of the heavens. This International Space Station shot taken 400 kilometres (250 miles) above Australia captures both. The orange airglow enveloping Earth happens when molecules (for the most part nitrogen and oxygen) are energized by sunlight, with its ultraviolet radiation. The Milky Way extends above this.
