New Horizons finds possible ice volcanoes on Pluto

From possible ice volcanoes to twirling moons, NASA’s New Horizons science team is discussing more than 50 exciting discoveries about Pluto at this week’s 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences. The two cryovolcano candidates are large features measuring tens of miles across and several miles high.

New Horizons’ manoeuvres put it on course for post-Pluto rendezvous

NASA’s New Horizons spacecraft, speeding toward deeper space at more than 32,000 miles per hour, has successfully performed a series of targeting manoeuvres that set it on course for a January 2019 encounter with Kuiper Belt object 2014 MU69. This ancient body is more than a billion miles beyond Pluto. The propulsive manoeuvres were the most distant trajectory corrections ever performed by any spacecraft.

Latest New Horizons images of Pluto and Charon delight and amaze

New close-up images of Pluto from NASA’s New Horizons spacecraft reveal a bewildering variety of surface features that have scientists reeling because of their range and complexity. Images downlinked in the past few days reveal new features as diverse as possible dunes, nitrogen ice flows oozing out of mountainous regions onto plains, and even networks of valleys possibly carved by material flowing over Pluto’s surface.

Extended haze in Pluto’s atmosphere

Backlit by the Sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometres) from the dwarf planet.

New Horizons discovers flowing ices on Pluto

NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect.
