A spectacular sampling of imagery from NASA’s New Horizons spacecraft reveals mountains and water ice bedrock on Pluto, an active crust on its largest moon Charon and the first resolved views of the icy world’s tiny mini-moons.
A snapshot of Pluto shows fresh deposits of water ice bedrock and 11,000-foot mountains, revealing evidence Pluto’s surface is one of the youngest in the solar system.

The first resolved image of the object shows it to be 28 miles long and 19 miles in diameter, and better images are to come. Credit: NASA/JHUAPL/SWRI
New results from NASA’s New Horizons mission, which zipped about 7,700 miles from faraway Pluto on Tuesday, show puzzling icy landforms covered in frozen carbon monoxide and mysterious dark smudges, which may be evidence for plumes erupting from Pluto’s warmer interior, scientists said Friday.
Fresh views from NASA’s New Horizons spacecraft released Thursday reveal diverse landscapes on Pluto, possible dune fields, mysterious channels, and nitrogen ice flows in greater detail than ever before, but it is just the tip of the iceberg as data from the far-flung probe resumes streaming back to Earth.
Thirteen years outbound from Earth and a billion miles past Pluto, NASA’s New Horizons probe is healthy and on course for a historic New Year’s Day flyby of its next target, a frozen remnant left over from the birth of the solar system 4.6 billion years ago, project scientists say.
