Global stereo mapping of Pluto’s surface is now possible (requires red/blue glasses for viewing in 3-D), as images taken from multiple directions are downlinked from NASA’s New Horizons spacecraft. Stereo images will eventually provide an accurate topographic map of most of the hemisphere of Pluto seen by New Horizons, which will be key to understanding the dwarf planet’s geological history.
A new close-up image of Pluto from New Horizons reveals a vast, craterless plain that appears to be no more than 100 million years old. This frozen region is north of Pluto’s icy mountains, in the centre-left of the heart feature, informally named “Tombaugh Regio” (Tombaugh Region) after Clyde Tombaugh, who discovered Pluto in 1930.
ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, saw a bright comet plunge toward the Sun on 3-4 August 2016, at nearly 1.3 million miles per hour. The comet, first spotted by SOHO on 1 August, is part of the Kreutz family of comets, a group with related orbits that broke off of a huge comet several centuries ago.
