New maps produced from data gathered during the New Horizons spacecraft’s flyby of Pluto last year show surprisingly widespread water ice shaping mountains capped by methane snow and forming an underlying bedrock blanketing the distant world.

News

Pluto’s floating mountains, intriguing structures fascinate scientists

January 5, 2016 William Harwood

Nearly six months after NASA’s New Horizons probe zoomed past Pluto, just one quarter of the data stored on board has made its way back to waiting scientists, revealing a surprisingly varied terrain that includes glacial flows and steep mountains of frozen water floating in a “sea” of slush-like nitrogen ice.

News

Rugged swath of Pluto now resolved in color

See the highest-resolution snapshots from July’s Pluto flyby

December 4, 2015 Stephen Clark

Scientists are marveling at some of the best views of Pluto recorded by the New Horizons spacecraft during its July 14 flyby of the unexplored icy dwarf in a set of photos released Friday showing Pluto’s icy, rugged topography in eye-popping detail.

News

‘Weird’ mountains on Pluto may be ice volcanoes

November 9, 2015 Stephen Clark

Maps of Pluto charted using data from NASA’s New Horizons mission appear to show two huge mountains scientists said Monday could be ice volcanoes, a discovery that would set the distant dwarf planet apart among its neighbors in the outer solar system.
