![]() The huge, encompassing heart-shaped region already bears the last name of Clyde Tombaugh, the late American astronomer who discovered Pluto in 1930. Tenzing Norgay was the Sherpa guide for Sir Edmund Hillary when they conquered Mount Everest in 1953. The peaks are now known, informally at least, as the Norgay Montes. The plains are the mountains' neighbors to the north. On Wednesday - just one day after the historic flyby - Stern and his team unveiled zoom-in photos showing 11,000-foot mountain ranges on Pluto, akin to the Rockies here on Earth. "I'm a little biased, but I think the solar system saved the best for last," Stern, a Southwest Research Institute planetary scientist, told reporters.Īn overlay of data from the New Horizons spacecraft that for the first time identifies the location of a carbon monoxide-rich region on Pluto. It represented the last planetary stop on NASA's grand tour of the solar system, begun a half-century ago. The spacecraft on Tuesday became the first visitor to the 4.5 billion-year-old Pluto, sweeping within 7,700 miles of its icy surface after a journey of 9 1/2 years. The fields of pits resemble glacial fields on Earth.Īs of Friday's news conference, New Horizons was just over 2 million miles past Pluto and operating well. ![]() It could be the hills were pushed up from below, or are knobs surrounded by eroded terrain, according to Moore. The height of the hills is not yet known, nor their origin. The plains - which include clusters of smooth hills and fields of small pits - are covered with irregular-shaped, or polygon, sections that look to be separated by troughs. He stressed that scientists have no hard evidence of erupting, geyser-like plumes on Pluto - yet.Īnother possibility could be that the terrain, like frozen mud cracks on Earth, formed as a result of contraction of the surface. "This could be only a week old for all we know," Moore said. Scientists speculate internal heating - perhaps from icy volcanoes or geysers- might still be shaping these crater-free regions. Like the mountains unveiled Wednesday, the plains look to be a relatively young 100 million years old - at the most. Spanning hundreds of miles, the plains are located in the prominent, bright, heart-shaped area of Pluto. "I mean, the landscape is just astoundingly amazing." "I'm still having to remind myself to take deep breaths," added Jeff Moore, head of the New Horizons geology team at NASA's Ames Research Center in California. Stern described the pictures coming down from 3 billion miles away as "beautiful eye candy." "Who would have expected this kind of complexity?" ![]() "Have a look at the icy frozen plains of Pluto," principal scientist Alan Stern said during a briefing at NASA headquarters. The New Horizons spacecraft team revealed close-up photos of those plains, which they're already unofficially calling Sputnik Planum after the world's first man-made satellite. Vast frozen plains exist next door to Pluto's big, rugged mountains sculpted of ice, scientists said Friday, three days after humanity's first-ever flyby of the dwarf planet. ![]()
