Stunning New High-Res Images Show Pluto In Even Greater Detail

NASA’s New Horizons spacecraft is sending back high-resolution images of Pluto showing the surface of the distant world with an even greater level of detail.

The new images, which were taken during a flyby over the summer, have allowed scientists to examine specific features in the terrain. This image — a synthetic perspective made from the high-resolution photos — shows the dark Cthulhu region at the bottom along with the smooth icy plains called Sputnik Planum (the nicknames are informal until they’re approved by the International Astronomical Union):

“If an artist had painted this Pluto before our flyby, I probably would have called it over the top,” New Horizons principal investigator Alan Stern of the Southwest Research Institute said in a news release. “But that’s what is actually there.”

Here’s an even closer look at the icy plains of Sputnik Planum, which shows features as small as a half mile in size:

Stern said the images reveal “a diversity of landforms and complexity of processes that rival anything we’ve seen in the solar system.”

That diversity includes what appear to be dunes:

“Seeing dunes on Pluto — if that is what they are — would be completely wild, because Pluto’s atmosphere today is so thin,” said William B. McKinnon, deputy lead of the New Horizons Geology, Geophysics and Imaging (GGI) team at NASA’s Ames Research Center in Moffett Field, California. “Either Pluto had a thicker atmosphere in the past, or some process we haven’t figured out is at work. It’s a head-scratcher.”

The “dunes” are the dark aligned ridges appearing near the center of the image, seen with what NASA describes as “ancient, cratered terrain” near the bottom and “bright, smooth geologically young terrain” up top.
