NASA's New Horizons takes 'best close-ups' of Pluto

The US space agency has released a series of sharp Pluto snapshots, billing them as the best close-ups of the dwarf planet we may see for decades.

On July 14, NASA's New Horizons became the first spacecraft to pass by Pluto, offering scientists unprecedented insight.

Previously released high-resolution images from that historic flyby have revealed unparalleled geographical variety on the planet, from soaring mountains, to sand dunes and frozen ice floes.
