Senior Editor and Planetary Evangelist, The Planetary Society

Two visits with the Planetary Society Senior Editor this week, as Emily first provides an update on the Rosetta comet mission and then returns with an extended look ahead at the New Horizons Pluto encounter next week. We also hear from Bill Nye the Science Guy, and Bruce Betts shares a new Random Space Fact as we explore what’s up in the night sky.

Pluto and Charon in color: LORRI + MVIC, June 25 & 27, 2015
Pluto shows two remarkably different sides in these color images of the planet and its largest moon Charon taken by New Horizons on June 25 and June 27. The images were made from black-and-white images combined with lower-resolution color data. The left image shows the side of Pluto that will be seen at highest resolution when New Horizons makes its close approach on July 14. The hemisphere is dominated by a very dark region that extends along the equator. The right image is of the side that faces Charon; the most dramatic feature on this side of Pluto is a row of dark spots arranged along the equator. (The equator appears near the bottom of the images of both Pluto and Charon, as New Horizons' view is mostly of their northern hemispheres.)
