Take a sneak peek at Pluto

The icy plains of Pluto resolved by NASA’s New Horizons spacecraft stretch as wide as Texas, enveloping mountain ranges and bizarre hilly outcrops in a mosaic revealing one lobe of the distant world’s heart-shaped reservoir of exotic frozen carbon monoxide, nitrogen and methane.

Sprawling across Pluto’s icy landscape is an unusual geological feature that resembles a giant spider. This enhanced colour image, obtained by NASA’s New Horizons spacecraft on 14 July 2015, consists of at least six extensional fractures (arrowed) converging to a point near the centre. Curiously, the spider’s “legs” expose red deposits below Pluto’s surface.

In a tantalising preview of what the surface of Pluto’s largest moon will look like in sharper future close-ups from NASA’s New Horizons spacecraft, this image from 1.5 hours before closest approach shows a depression with a peak in the middle.
