From a distance of 450,000 kilometres (280,000 miles) away, New Horizons’ Long Range Reconnaissance Imager (LORRI) took four photos to create this composite colour image of Pluto, revealing some curious details. The heart-shaped Tombaugh region (named after the astronomer who discovered Pluto in 1930) is split into two lobes in this image, and it’s thought that temperatures as low as -223 degrees Celsius (-369 degrees F
