Decades of space photography has revealed a considerable amount of information and has produced incredible imagery that happens to have an artistic aesthetic.

"In 1992, the Jupiter-bound Galileo spacecraft made a pass by our planet’s closest companion, the moon. This mosaic of 53 images shows the different composition of rocks on the moon's surface. Blue and orange colors represent lava flows, bright pink areas are highlands, and light blue colors indicate recent impact material with the youngest craters showing blue rays extending away from them."

"When NASA’s Voyager 1 mission zipped by the Jupiter system in 1979, it discovered that far from the sun were worlds of incredibly active worlds. In particular, it shot spectacular pictures of the moon Io, which is covered in volcanoes and is now known to be one of the most geologically active places in the solar system. This image shows a plume from a volcano on Io’s surface."
