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.
