NASA's Evolving Views of Pluto

NASA's New Horizons spacecraft flew within 8,000 miles of dwarf planet Pluto on 14 July 2015. Our view of this cold, previously unexplored world, 4.67 billion miles from Earth, has evolved since its discovery by Clyde W. Tombaugh in 1930. This short clip shows images from Tombaugh, Hubble and New Horizons over the years, arranged to illustrate improvements in resolution.

The close-up image at the end of this clip was taken about 1.5 hours before New Horizons closest approach to Pluto, when the craft was 47,800 miles (77,000 kilometers) from the surface of the planet. The image easily resolves structures smaller than a mile across.
