There really are no words.
The photo, taken by Japanese astronaut Koichi Wakata last weekend, shows the moon, the Earth’s atmosphere and the nighttime Earth.
The Sun is behind the Earth, and you can see it lighting a crescent of the moon and shining through the Earth’s atmosphere.
The lowest reaches of the atmosphere are red, because only the longest wavelengths of visible light, which are red, aren’t scattered by the dense air. The upper atmosphere, which is not at all dense, allows for the emission of even the shortest wavelengths of light, blue, indigo and violet.
It makes for a stunning portrait of our world.
Arigatō, Mr. Wakata.
