Ready for another dose of Pluto news? Of course you are! During an event today, NASA shared its latest discoveries in regards to the icy dwarf planet. First, detailed imagery from New Horizon's Long-Range Reconnaissance Imager (LORRI) shows "geologic activity" on the surface that includes flowing ice on a plain known as Sputnik Planum. That area lies in the western part of that massive heart-shaped region you've likely noticed in photos. NASA says the ice there flowed, and may still be flowing now, in a way that resembles the movement of glaciers on Earth. In the southern portion of Sputnik Planum, researchers discovered a range of icy mountains that rise about a mile and can be compared to the Appalachian Mountains here in the States. In fact, the peaks have been informally named Hillary Montes and are located near another range named Norgay Montes. The names are in honor of Sir Edmund Hillary and Tenzing Norgay -- explorers who first reached the summit of Mount Everest in the 1950s.
