At first glance, these vivid images look like abstract paintings. But look again and you’ll realize that they are actually photographs of earth from space. The satellites used to take these photographs break up the image into ‘spectral bands’, which separate the light (both visible and invisible) into different wavelengths, resulting in these surreal images. NASA has compiled a selection of fascinating photographs of the earth from over the last 40 years into a book entitled, Earth as Art. I don’t know about you, but I’d hang one of these photographs on my wall.
