Astronomy Day

Get your telescope and star map app ready because it"s Astronomy Day! Doug Berger, then president of the Astronomical Association of Northern California, created Astronomy Day in 1973 to get more people interested in the wonders of space. He set up telescopes on street corners, malls, and parks to give people a chance to see the stars firsthand.
