Blue skies on Pluto - ABC Breakfast News TV
Alan Duffy
I spoke about the Apollo Archival Project putting thousands of Apollo era photos on flickr at https://www.flickr.com/photos/projectapolloarchive/albums and then the discovery that Pluto has blue skies..! We take this for granted on Earth but it's actually really unusual in our solar system, the atmosphere should be too thin in Pluto for this but it gets a helping hand from organic gunk in the air called tholins that then stain the surface red.
