Astronomy Day

 The Founder of International Astronomy Day, Doug Berger, gives a rare interview on the 45th Global Star Party
The Next Astronomy Day is May 18th, 2024

International Astronomy Day is celebrated to promote interest in astronomy and to offer people a chance to experience the beauty and fascination of the night sky. This event encourages public participation in observation sessions, educational programs, and other activities related to astronomy. It aims to bring astronomy closer to the public, highlighting how it plays a significant role in our culture and society.

Astronomy Day was started in 1973 by Doug Berger, the then-president of the Astronomical Association of Northern California. The event was designed to increase public awareness about astronomy and to bring enthusiasts and professionals together to share their knowledge and passion. Initially held in the fall, the celebration was so successful that it was expanded to include a spring event as well. Therefore, International Astronomy Day is now celebrated twice a year - once in the spring and again in the fall. The spring event is scheduled to occur on a Saturday closest to the first quarter Moon between mid-April and mid-May, and the fall event occurs on a Saturday closest to the quarter Moon from September to October.

Activities on International Astronomy Day can include public observation sessions with telescopes, planetarium shows, astronomy-related workshops, presentations by astronomy experts, and other educational events. These activities are usually organized by planetariums, observatories, universities, and astronomy clubs around the world, making it a global celebration of the wonders of the universe.
