MEXICO: New sharp images of Pluto have revealed a bewildering variety of surface features that have left scientists reeling because of their range and complexity.
Taken from NASA’s New Horizons spacecraft, the images reveal new features as diverse as possible dunes, nitrogen ice flows that apparently oozed out of mountainous regions onto plains, and even networks of valleys that may have been carved by material flowing over Pluto’s surface.
“Pluto is showing us a diversity of landforms and complexity of processes that rival anything we have seen in the solar system,” said New Horizons principal investigator Alan Stern from Southwest Research Institute (SwRI), Boulder, Colorado.
New Horizons has begun its year-long download of new images and other data.
They show large regions that display chaotically jumbled mountains reminiscent of disrupted terrains on Jupiter’s icy moon Europa.
“The surface of Pluto is every bit as complex as that of Mars,” added Jeff Moore from Nasa’s Ames Research Center in California.
The randomly jumbled mountains might be huge blocks of hard water ice floating within a vast, denser, softer deposit of frozen nitrogen within the region informally named Sputnik Planum, he explained.
New images also show the most heavily cratered and thus oldest terrain yet seen by New Horizons on Pluto next to the youngest, most crater-free icy plains.
