Nasa’s New Horizons probe has begun sending back images of Pluto from the outer edge of our solar system.
But it will be 16 months before all the data arrives back on earth.
However a number of amateur astronomers have begun working on some of the images so far received.
BBC Click’s Lara Lewington went to meet one keen sky watcher to see what we have learned from the data so far.
