THE DISCOVERY
THE PLUTO DISCOVERY The search for the elusive ninth planet had been ongoing for over three decades since the turn of the 20th century. Precise observations of the orbits of Uranus and Neptune had suggested another distant world lurking in the darkness beyond Neptune. However, locating such a faint object was like searching for a needle in the celestial haystack. Leading the hunt for Planet X during this time was Percival Lowell, founder of the Flagstaff Observatory. Starting in 1906, Lowell had embarked on an obsessive pursuit of the ninth planet. Despite years of work though, he would not live to see its discovery, nor know how close he had come to finding it himself. Unbeknownst to Lowell, images of Planet X had been captured in two photographs he took just a year before his death in 1916. However, the evidence was overlooked as the plates were filed away, and the search continued without him for another 15 years.
