Pluto from Earth and NASA's New Horizons spacecraft
Leslie Young



When NASA's New Horizons spacecraft flew past the Pluto system in July 2015, it revealed a beautiful, varied, and puzzling system. Pluto's surface ranges from dark and cratered terrains and tall mountain ranges, to compositionally varied highlands and geologically young ice flows. Charon sports a completely unexpected dark, reddish area near its north pole. Pluto's atmosphere is hazy out to hundreds of km -- particularly astonishing since Pluto itself is only about 1200 km in radius. I will discuss these and other news from the New Horizons spacecraft. The success of these observations stand on the foundation laid by observations at Mauna Kea and elsewhere, and raise further questions that will also be answered from earth-based or near-earth telescopes.
