Gorgeous Pluto! The dwarf planet has sent a love note back to Earth via our New Horizons spacecraft, which has traveled more than 9 years and 3+ billion miles. This is the last and most detailed image of Pluto sent to Earth before the moment of closest approach, which was at 7:49 a.m. EDT Tuesday - about 7,750 miles above the surface -- roughly the same distance from New York to Mumbai, India - making it the first-ever space mission to explore a world so far from Earth. This stunning image of the dwarf planet was captured from New Horizons at about 4 p.m. EDT on July 13, about 16 hours before the moment of closest approach. The spacecraft was 476,000 miles (766,000 kilometers) from the surface. Images from closest approach are expected to be released on Wednesday, July 15.

Blue Doors | Namibia I've been dying to take this shot for years and I've finally gotten around to it! Kolmanskop was a German diamond mining town founded in southern Namibia in 1908. The diamond supply eventually ran out and the town was abandoned in 1954. Since then, the harsh Namib desert has started reclaiming it. It had the first tram in Africa and the first X-ray station in the Southern Hemisphere. Cool stuff! Big thanks to @instagram for featuring this shot on their blog! #africa #namibia #kolmanskop #kolmannskuppe #abandoned #mining #town #diamonds #diamond #sand #dunes #door #doors #nature #iphone #iphone5 #iphoneonly #igmasters #town #ghost #ghosttown #iphone_only #namib #desert #architecture #travel #amazing #beautifuldestinations #earthfocus #travelstoke
