Scientists released a sneak peek of Pluto taken by New Horizons around 2000 GMT Monday at a range of 766,000 kilometres (476,000 miles), about 16 hours before closest approach.

This ethereal scene captured by NASA’s New Horizons spacecraft tells yet another story of Pluto’s diversity of geological and compositional features — this time in an enhanced colour image of the north polar area. A canyon about 45 miles wide runs close to the north pole, its degraded walls suggesting evidence for an ancient period of tectonics.
Scientists planning the the next phase of NASA’s New Horizons mission, a robotic craft that completed the first exploration of Pluto in 2015, are going into the flyby of a frozen, faraway city-sized clump of rock on New Year’s Day 2019 armed with little knowledge of the target lurking around 4 billion miles from Earth.
This processed image is the highest-resolution colour look yet at the haze layers in Pluto’s atmosphere. Shown in approximate true colour, the picture was constructed from a mosaic of four panchromatic images from the Long Range Reconnaissance Imager (LORRI) splashed with Ralph/Multispectral Visible Imaging Camera (MVIC) four-colour filter data, all acquired by NASA’s New Horizons spacecraft on 14 July 2015.
