Happy International Astronomy Day!

Ever wondered what Saturn"s rings look like through a telescope? Or how astronomers spot distant galaxies? International Astronomy Day is the perfect time to find out. This annual event, first launched in 1973, is all about "Bringing Astronomy to the People"—the official theme of Astronomy Day. From local parks to astronomy clubs, museums, and observatories, visitors can enjoy activities like telescope viewings, space talks, and even moon gravity simulators.
