It seems that the more we see of Pluto, the more fascinating it gets. This latest image, from the heart of Pluto’s heart feature, shows the plains’ enigmatic cellular pattern as well as unusual clusters of small pits and troughs. Adding to the intrigue is that even at this resolution of 250 metres, no impact craters are seen, testifying to the region’s extreme geologic youth.
A subsurface ocean lies deep within Saturn’s moon Dione, according to new data from the Cassini mission. Two other moons of Saturn, Titan and Enceladus, are already known to hide global oceans beneath their icy crusts. Researchers believe that Dione’s crust floats on an ocean several tens of kilometres deep located 100 kilometres below the surface.
