This page features my favorite images of Pluto, taken by New Horizons, a NASA space probe.
New Horizons was launched on January 19th 2006 and sent on a 9 year+ journey to Pluto and beyond. New Horizons made its closest approach to the distant planet of Pluto on the 14th of July, 2015.
Travelling at up to 32,500 miles per hour on the closest approach, New Horizons came within 7,750 miles of the planets surface. Up until this time, Pluto was the only planet in the solar system (of the 'historical eight') which had never been visited by a spacecraft.
When the first images of Pluto came back, they were taken a considerable distance away and the image quality was not so good. However, as New Horizons got closer to Pluto, more detailed images of this planet (and neighboring moon, Charon) were down-linked to Earth (albeit very slowly). Scientists were hoping to see objects on the planet as little as 200 feet across (about the size of a Boeing 747 aeroplane).
This is a sample of the best images of Pluto I think have been released to the public so far.
