Astronomy Day was founded in 1973 by the Astronomical Association of Northern California, and is scheduled for a Saturday nearest the first quarter Moon between mid-April and mid-May. This allows participants to include observations of the Moon (weather-permitting) in the day's proceedings. This event is celebrated by astronomy clubs, planetariums, science centers, observatories, and other astronomy-oriented organizations who are eager to share their enthusiasm and interest in all things celestial.
Astronomy Day 2019
Discover the joys of stargazing with amateur and professional astronomers, students, scientists, and technology innovators as we celebrate Astronomy Day in the Piazza from 10am to 4pm! Academy visitors can observe or participate in activities, demonstrations, and crafts, or ask astronomy and space-related questions at any of the tables. Young visitors can enjoy a space-age Interstellar Story Time at 10:45am and 1:45pm at Science Today. Weather-permitting, you can stargaze from the Living Roof (one star can be seen up-close: the Sun). Later in the day, observe the craters on the Moon!
