NASA’s New Horizons space probe launched on Jan. 19, 2006, and has been snapping pictures as it approached Pluto.

It flew within 6,000 miles of Pluto on Tuesday morning, resulting in the closest and best images of Pluto humankind has ever seen. Over the course of its travel in the past year, as the gif shows, some of the snaps of Pluto have been far less than crisp.
