Peering closely at the "heart of Pluto," in the western half of what mission scientists have informally named Tombaugh Regio (Tombaugh Region), New Horizons' Ralph instrument revealed evidence of carbon monoxide ice.
Nave de la NASA descubre forma de corazón ♥ en Plutón
Scientists using NASA’s Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system’s outermost regions.
Pictures of Pluto's largest moon Charon have also allowed scientists to see enormous chasms and craters on the surface. A 200 mile wide dark region around the north pole has proved to be particularly baffling
Hidden Oceans on Jupiter's Icy Moon Europa May Explain Strange Terrain
This rendering of Europa shows the temperature field in a simulation of the icy Jupiter moon's global ocean dynamics, where hot plumes (red) rise from the seafloor and cool fluid (blue) sinks down from the ice-ocean border. More heat is delivered to the ice shell near the equator, consistent with the distribution of chaos terrains on Europa. Image released Dec. 1, 2013.
The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon’s makeup.
