Sunset on Pluto: Breathtaking NASA Photo Shows Mountains, Wispy Atmosphere!

A spectacular new image from NASA's New Horizons spacecraft shows Pluto in an entirely new light.

The photo, which New Horizons took during its epic July 14 flyby of Pluto, captures a gorgeous sunset view. Towering ice mountains cast long shadows, and more than a dozen layers of the dwarf planet's wispy atmosphere are clearly visible.

'This image really makes you feel you are there, at Pluto, surveying the landscape for yourself," New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado, said in a statement today (Sept. 17). "But this image is also a scientific bonanza, revealing new details about Pluto's atmosphere, mountains, glaciers and plains." [See more Pluto photos by New Horizons] losest approach to Pluto

.The spacecraft turned back and looked toward the sun, snapping the photo at a distance of just 11,000 miles (18,000 km) from the dwarf planet, NASA officials said. (At closest approach, New Horizons was about 7,800 miles, or 12,550 km, from Pluto's surface.)

The result was a new perspective on Pluto's Norgay Montes and Hillary Montes, two ranges of ice mountains that rise up to 11,000 feet (3,500 meters) above the dwarf planet's frigid surface. The backlit photo also reveals new details about Pluto's nitrogen-dominated atmosphere, showing many different layers, extending from ground-bound fog to wispy tendrils more than 60 miles (100 km) up.

Observatory in Flagstaff, Arizona, said in the same statement.

The new panorama and other recently downloaded New Horizons images also shed light on how ice — likely made of nitrogen and other materials rather than water — flows into a vast, flat glacial plain known as Sputnik Planum. Some of Sputnik Planum's ice apparently evaporates, gets deposited in a region of rough terrain to the east and then flows back down into the plain as glaciers, via a system of valleys.

These glaciers are similar to those seen in Greenland and Antarctica here on Earth, researchers said.

comparable to the hydrological cycle that feeds ice caps on Earth, where water is evaporated from the oceans, falls as snow and returns to the seas through glacial flow."

"Pluto is surprisingly Earth-like in this regard, and no one predicted it," Stern added.

New Horizons beamed the new backlit panorama home to mission control on Sunday (Sept. 13), and NASA released the photo today.

The world can expect to see many more stunning new views from the Pluto flyby over the coming year or so. New Horizons relayed just 5 percent of its flyby data back in the immediate aftermath of the close encounter, keeping the vast majority on board for later transmission. That data dump began in earnest earlier this month and is expected to take about 12 months, New Horizons team members have said.
