The colours are real, just have been enhanced to allow the human eye to distinct chemical, mineralogical, and physical regions across the planet's cratered surface. NASA's Messenger spacecraft has given scientists the best ever view of Mercury, the nearest planet to the Sun.

The huge circular, tan coloured feature in the upper right of the image is the Caloris basin which was created by a giant impacting comet or asteroid early in the planet's history. This ancient basin was subsequently flooded with lava from volcanic activity.

The light blue and white streaks are lines or 'rays' caused by material blasted out of younger craters from more recent impacts. The darker blue regions are low reflectance terrains which are still investigated by scientists.

Messenger became the first spacecraft to enter orbit around Mercury on March 18, 2011. As well as providing the first complete map of the planet's surface, Messenger is also answering key questions about Mercury's geologic history and composition, its magnetic field, whether it has ices at its poles, and where its very thin atmosphere comes from.
