This time last year, space enthusiasts all over the world were eagerly awaiting photos of Pluto. As NASA's New Horizons spacecraft zipped toward its July 2015 flyby of the Pluto system, every image it sent home was the best, clearest image we'd ever seen.

Far in the western hemisphere, scientists on NASA's New Horizons mission have discovered what looks like a giant "bite mark" on Pluto's surface.

NASA's New Horizons spacecraft has captured images of frozen nitrogen glaciers on Pluto carrying numerous 'floating' hills that may be fragments of water ice, giving an insight into the dwarf planet's fascinating and abundant geological activity.

From possible ice volcanoes to twirling moons, NASA's New Horizons science team is busy analysing more than 50 exciting discoveries about Pluto that the probe has revealed so far.

Pluto is a "fascinating" world with a diverse range of landforms such as smooth plains, ice mountains and bladelike ridges, according to the first research paper from a flyby of the dwarf planet in July.

The New Horizons probe has found a second mountain range situated between bright, icy plains and dark, heavily-cratered terrain on the lower-left edge of Pluto.
