I am super exited about New horizons mission, what it represents and what it stands for. I can’t wait for proper hight resolution images. As of now, the best what we have is 1024 x 1024 pixels image of Pluto and 1050 × 794 image of Charon. Pluto it is for my 4K screen and Charon for retina macbook pro !

Image of Charon adjusted for Retina MacBook Pro
