The photo above shows a sight that can only be seen from space: The Moon against a black sky, with the Earth in daylight. Fewer than .00001% of the world’s population have had the opportunity to see this sight. That number will increase dramatically in the next few years, when suborbital spaceflight becomes commercially available.
At first glance, the Moon appears oddly dark. We think of the Moon as being quite bright, almost pure white. That’s because we’re used to viewing the Moon at night when our eyes are dark adapted. Of course, the Moon isn’t really white, or light in color, at all. The observations and photos taken by the Apollo astronauts, the samples they brought back, all prove that. Viewed alongside the oceans and clouds of Earth, the Moon shows its true color in this photograph.
The Moon also appears unusually small in this photo. That is due to the well-known Moon illusion, or rather the lack of a Moon illusion. When we observe the Moon in the night sky, our brains trick us into seeing the Moon as larger than it really is. That doesn’t happen when you look at a photograph of the Moon. The photo above is optically accurate, but the photo below has been altered to show the scene as you might actually perceive it from space, due to the Moon illusion:
