New global map of Pluto

29 July 2015 Astronomy Now

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.

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.


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.
