Cosmic Lava Lamp

Explanation: Scientists from NASA's New Horizons mission used state-of-the-art computer simulations to show that the surface of Pluto's informally named Sputnik Planum is covered with churning ice "cells" that are geologically young and turning over due to a process called convection. The scene above, which is about 250 miles (400 kilometers) across, uses data from the New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC), gathered July 14, 2015.
