History of International Astronomy Day
Doug Berger started the celebration of World Astronomy Day in 1973. He was the then president of the Astronomical Association of Northern California. He intended to set up various telescopes in busy urban locations so that people could get a peek at the universe. It was an attempt to raise the general public's interest in astronomy. The event received a remarkable response and was later expanded to other countries.
International Astronomy Day is now celebrated in many countries worldwide. Many organizations associated with astronomy sponsor the event. Moreover, people interested in science come together to join discussions around astronomy on this day.
Significance of Astronomy Day
Our curiosity about space has led to many advances in space technology to explore the vastness of the universe and improve our understanding of the cosmos. But it all began when a special branch of natural science called "astronomy" was developed to study celestial objects and phenomena in space.
As this science developed, it was used to explore space, and in honor of this unique branch of science, International Astronomy Day is celebrated every year. The Astronomy Day Spring celebration usually occurs between mid-April to mid-May, while the Autumn celebration occurs between September and October.
