For more than 80 years after Pluto's discovery in 1930, scientists had no real idea what it was like. Then NASA's one-of-a-kind spacecraft New Horizons blazed past on July 14, 2015 - the first probe ever to do so. As it did, cameras aboard captured the former planet up close. Instead of a bleak, ice-covered sphere, Pluto was revealed as a complex world with a blue sky, the largest glacier in the solar system, and where major activity is still occurring.
