i wandered about charonshine on pluto and
i watched this animation of the flyby and according to it there should be a good chunk of charonshine on the farside lighting up mapped parts and unmapped parts of the southern hemisphere in this image https://upload.wikimedia.org/wikipedia/comm...cklit_Pluto.jpg here is a pic from the animation showing potential charonshine on pluto can anyone like ted pull real charonshine from any of the pluto images, because theoretically there was a huge hunk of it visible during the flyby and i want to add it to known map coverage here is a whole gallery of raw pluto images for anyone to attempt charonshine extraction http://pluto.jhuapl.edu/soc/Pluto-Encounte...Date&page=9 |

"how didn't pluto blow up into tons of pieces"
An impact crater forms as an expanding shock from the impact excavates a transient cavity, which becomes the crater after other modifications (gravity, ejecta fallback etc). For a body to be blown apart the entire body has to be within that transient cavity. No observed impact crater from Stickney on Phobos to SPA on the Moon or Sputnik on Pluto comes close to that. If you can see a crater it was nowhere near blowing the object apart. Also, the drawings of Pluto are by James Tuttle Keane. Phil -------------------- ... because the Solar System ain't gonna map itself.

Phil James Tuttle Keane did a nice job at rendering the formation of sputnik so the impacter needs to be really really huge (almost the same size as pluto) and moving fast to destroy pluto |
