Pluto looms large in Flagstaff, where residents and businesses alike
take pride in their community's most enduring claim to fame: Clyde
Tombaugh's 1930 discovery of Pluto at Lowell Observatory. Percival
Lowell began searching for his theoretical Planet X in 1905, and
Tombaugh's eureka! experience brought worldwide attention to the city
and observatory. Ever since, area scientists have played leading roles
in virtually every major Pluto-related discovery, from unknown moons to
the existence of an atmosphere and the innovations of the New Horizons
spacecraft. Lowell historian Kevin Schindler and astronomer Will Grundy
guide you through the story of Pluto from postulation to exploration.
