Flagstaff, AZ. – February 18 marks the 92nd anniversary of Pluto’s discovery in northern Arizona. To celebrate, Lowell Observatory is partnering with other Flagstaff organizations in hosting the 3rd Annual I Heart Pluto Festival.

I Heart Pluto Festival Background

A northern Arizona Pluto celebration is appropriate: Flagstaff is often called the “Home of Pluto” because nearly every major research effort surrounding this icy world has ties to northern Arizona—Percival Lowell’s early searches for a ninth planet; Clyde Tombaugh’s discovery of Pluto on February 18, 1930; Jim Christy’s detection of Pluto’s largest moon, Charon, in 1978; the first observation of Pluto’s atmosphere in 1988; early maps of Pluto’s surface a decade later; the New Horizons flyby of the Pluto system in 2015, and more.


About Lowell Observatory

Lowell Observatory is a private, nonprofit 501(c)(3) research institution, founded in 1894 by Percival Lowell atop Mars Hill in Flagstaff, Arizona. The observatory has been the site of many important discoveries, including the first detection of large recessional velocities (redshift) of galaxies by Vesto Slipher in 1912-1914 (a result that led ultimately to the realization that the universe is expanding), and the discovery of Pluto by Clyde Tombaugh in 1930. Today, the observatory’s 14 tenured astronomers use ground-based telescopes around the world, telescopes in space, and NASA planetary spacecraft to conduct research in diverse areas of astronomy and planetary science. Lowell Observatory currently operates multiple research instruments at its Anderson Mesa station, east of Flagstaff, and the 4.3-meter Lowell Discovery Telescope near Happy Jack, Arizona. Prior to the pandemic, the observatory also welcomed more than 100,000 guests per year to its Mars Hill campus in Flagstaff, Arizona, for a variety of educational experiences, including historical tours, science presentations, and telescope viewing.
