Event Details

Lowell Observatory and Orpheum Theater present A Night of Discovery, a celebration to commemorate the anniversary of Clyde Tombaugh’s discovery of the icy world Pluto on February 18, 1930. Mingle with world-renowned scientists who push boundaries with discoveries that change how we look at our universe.

This is the keynote event of Lowell Observatory's 3rd Annual I Heart Pluto Festival.

Meet Eminent Scientists

Headlining this year’s event is a panel discussion that looks at our human need to explore and discover, from nearby nooks on Earth to the far reaches of the universe. The panel includes:


·       Dr. Donald Johanson, discoverer of the fossil hominid Lucy

·       Dr. Alan Stern, Principal Investigator of the New Horizons mission to Pluto and beyond

·       Dr. Nancy Currie-Gregg, astronaut who flew 4 times in space

·       Dr. Cathy Olkin, Deputy Principal Investigator of the Lucy mission to study asteroids

·       Alden Tombaugh, son of Pluto discoverer Clyde Tombaugh

·       Dr. Jeffrey Hall, Lowell Observatory Director, will moderate the discussion


The program will be followed by a panelist book signing. Books by several of the panelists, as well as commemorative posters and other items to be signed, will be available for purchase onsite.


Explore Space Art Displays

The International Astronomical Artists Association (IAAA) will display a variety of space-themed art throughout the Orpheum. The IAAA consists of artists and scientists-artists who implement and participate in astronomical and space art projects.


Quench Your Thirst with Lowell Observatory Lager

Back by popular demand is a Pluto-themed beer created specially for this event by Mother Road Brewing Company, Arizona’s third largest independent craft brewer. This year’s beer is Lowell Observatory Lager! Other drinks—both alcoholic an non-alcoholic—as well as food will be available for purchase throughout the evening.


Why the Orpheum?

Why hold this event at the Orpheum Theatre? Because Clyde Tombaugh watched a movie here on the night of his great discovery in 1930. Plus, the Orpheum accessibility, comfort, and old-time charm, make it a perfect venue.
