Pluto’s Moon Charon mapped

31 July 2015 Astronomy Now

The science team of NASA’s New Horizons mission has produced this global map of Pluto’s largest moon, Charon, from the data received so far from the 14 July flyby.

The science team of NASA’s New Horizons mission has produced an updated global map of dwarf planet Pluto that includes all resolved images of the surface acquired 7-14 July 2015, up to 400 metres/pixel resolution. Many additional images are expected in autumn 2015 and these will be used to complete the global map.

Close-up of Charon’s ‘Mountain in a Moat’

In a tantalising preview of what the surface of Pluto’s largest moon will look like in sharper future close-ups from NASA’s New Horizons spacecraft, this image from 1.5 hours before closest approach shows a depression with a peak in the middle.

Pluto and Charon as never seen before

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.

Scientists wowed by new views of ‘psychedelic’ Pluto

15 July 2015 Stephen Clark

Pluto and its Texas-sized moon Charon share an alien environment on the solar system’s outer frontier, with patches of organic ices and diverse rock types illustrated in color imagery released Tuesday.

How big is Pluto? New Horizons settles decades-long debate

13 July 2015 Astronomy Now

The true size of Pluto has been debated since its discovery over 85 years ago. New Horizons’ mission scientists can now answer that question with certainty, confirming that Pluto is larger than all other known Solar System objects beyond the orbit of Neptune.

Clear sailing expected for Pluto flyby

13 July 2015 Stephen Clark

There is no sign of an undiscovered moon lurking around Pluto in data streaming back to Earth from NASA’s New Horizons spacecraft, and that is surprising to Alan Stern, the scientist in charge of the probe.

How to find Pluto around the time of its historic encounter with New Horizons

5 July 2015 Ade Ashford

Dwarf planet Pluto will receive its first robotic emissary from Earth in the form of NASA’s New Horizons spacecraft on 14 July. Since this enigmatic world is also at opposition on 6 July, here’s our guide to finding Pluto with large backyard telescopes.

New Horizons sees Pluto’s close approach hemisphere and Charon’s ‘dark pole’

24 June 2015 Astronomy Now

NASA’s New Horizons spacecraft doesn’t pass Pluto until July 14th — zipping by about 7,800 miles (12,500 kilometres) above the surface of the dwarf planet after a journey of almost 3 billion miles — but the mission team is making tantalising new discoveries as the piano-sized probe bears down on the Pluto system.

Hubble observes chaotic dance of Pluto’s moons

4 June 2015 Astronomy Now

A comprehensive analysis of all available Hubble Space Telescope data shows that two of Pluto’s moons, Nix and Hydra, are wobbling unpredictably. Scientists believe the other two small moons, Kerberos and Styx, are likely in a similar situation, pending further study.
