Needle in a Haystack: How Clyde W. Tombaugh Found an Awesome New World

Farm boy and self-taught astronomer Clyde W. Tombaugh trained his homemade telescope on the planets almost every night. He drew the surfaces of Mars and Jupiter and shared his drawings with Lowell Observatory in Flagstaff, Arizona. Gadzooks! They hired him to search for a new planet! After 300 days of scouring the sky with a powerful telescope that could take photos, Clyde pinpointed Pluto’s location on February 18, 1930. His tenacity paid off— he found the last planet in the solar system. This 1280-word biography of Clyde W. Tombaugh is a confirmation of the twin pillars of success—passion and persistence. 


Arizonans are celebrating that Pluto has been named the State Planet by the state legislature.
