In the late 1950s, philanthropist Robert Maytag, the grandson of the Maytag Company founder, had a dream that the growing city of Phoenix needed a world-class zoo. Under Maytag's formidable vision and leadership, the dream became a reality in 1962. Now the Phoenix Zoo is one of the biggest privately owned, nonprofit zoos in the United States and one of the most visited places in Arizona. The zoo maintains a year-round staff of over 300 employees and covers 125 acres housing 3,000 animals, including 30 threatened or endangered species. Without much room to expand, the zoo utilizes its current space to rebuild and renovate. Since opening, the Phoenix Zoo has welcomed more than 43 million visitors through its gates, fulfilling its mission of providing experiences that inspire and motivate people to care for the natural world.

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.

Atop a mesa one mile west of downtown Flagstaff, Arizona, sits Lowell Observatory, an astronomical research facility steeped in tradition. Percival Lowell, scion of a Boston Brahmin family, initially established his observatory in 1894 to study the possibility of intelligent life on Mars. Lowell widely popularized his controversial theories, sparking debate among both the scientific community and lay public. In the following years, the observatory's astronomers made several discoveries that dramatically altered our understanding of space, including Clyde Tombaugh's discovery of Pluto in 1930 and V.M. Slipher's detection of the expanding nature of the universe in 1912. Decades later, Apollo astronauts visited as part of their training to fly to the moon. These stories and others offer a glimpse of the scientific discovery, community pride, and personal triumph that define Lowell Observatory.
