Space History Made on March 19, 1915

On this day in 1915 Pluto was photographed for the first time. At the time it was not known that Pluto was in the photo. On February 18 1930 Pluto was discovered (in the photos above) and upon reviewing older photos it was found that it had been first photographed in 1915. Of course today Pluto is no longer classified as a planet but it still was a an exciting discovery. Pluto had been right under astronomers noses for 15 years unnoticed.
