This Week in Photography History Clyde Tombaugh discovered the dwarf planet Pluto on February 18, 1930 through examining photographs of the section of sky beyond Neptune. Photographs were taken over a period of time using an astrograph, essentially a telescope for celestial photography, thirteen inch long with three elements set for f5.3. By using a machine that rapidly switched between photos, he identified the one moving object as a new planet. Image via Science Blogs
