This Is What Leaving Earth Behind Really Looks Like

Prepare yourself for some goosebumps. The Mercury spacecraft MESSENGER took this series of images of Earth eight years ago today as it swung by the planet (again) en route to its final destination.

Few humans have seen the Earth as an entire orb. Only a handful of missions, all in the Apollo era, have ventured beyond low Earth orbit. The people who traveled furthest were Jim Lovell, Fred Haise and Jack Swigert during Apollo 13, when their spacecraft (which had been

crippled by an explosion

) looped around the moon on the way home.

MESSENGER is happily traveling around Mercury these days and recently

recorded a cool series of images

showing the planet as a colorful, spinning sphere. The spacecraft -- the first to do an extended stay around that planet -- has

shown scientists a lot of things

, including the discovery of water ice and organics.
