NASA is unveiling mosaics of Pluto and its largest moon Charon, representing the global response to its popular “#PlutoTime” social media campaign. A photo of Clyde Tombaugh, the American who discovered Pluto in 1930, is embedded in this mosaic of hundreds of images shared during the campaign. #happyFriday space fans! #tagafriend and pass this one on, they just might be part of the picture!
