Have you ever looked up into the night sky and wondered about rovers exploring the surface of Mars, how Galileo used a small telescope to discover four moons of Jupiter, or how astronomers create those beautiful images of galaxies? During this event to honor National Astronomy Day, guests will find out answers to these questions and discover lots more amazing things about the universe and how it works. They will conduct their own experiments, observe the night sky through the Museumâ€™s rooftop telescopes, watch planetarium and laser shows, and listen to keynote speaker Professor Rafael Guzman, Chair of the Department of Astronomy at the University of Florida, who will talk about the largest optical telescope on Earth, the Gran Telescopio de Canarias. The event will also feature an exhibition of images of outer space created by students and with support from the Smithsonianâ€™s Youth Capture the Colorful Cosmos program. Guests can even safely observe the Sun with solar telescopes from the Southern Cross Astronomical Society. On Friday evening, guests will enjoy observing the night sky on the rooftop.
