This thread is for discussion of NH Pluto surface observations received after 10 Oct 2015.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

A lot of images have been released of Pluto's night side on the LORRI page. Charonshine imaging?

At the time those images were taken (July 15, ~1:50 UTC), half of Pluto's night side was visible from Charon; the other half was not. So if there is something to see there, we should see that one side of the dark disc is lit with a gradation towards total darkness on the other half.
As the attached text notes, the Sun is not too far from the direction of the camera. That is a problematic factor: If NH had a view of Pluto's entire dark side, and Charon were illuminating the entire dark side, then the Sun would be right in the line of sight. When you add in that Pluto's atmosphere is scattering light, the signal:noise for Charonshine images may be unfavorable. The atmosphere was not a problem with, e.g., Saturn and Iapetus. |
