This Saturday, May 2nd, is Astronomy Day. MOSI will be celebrating Astronomy Day and the International Year of Astronomy with astronomy related activities throughout the day and during the evening. The M.A.R.S. Club, our local astronomy club, will be here to answer questions and provide information. We will have astronomy themed demonstrations by MOSI's interactors. You can look at the Sun through MOSI's solar telescopes during the day (weather permitting). Saturn and the Moon will be two of the sights during SkyWatch from 8 to 10 p.m. (weather permitting).

The offerings in The Saunders Planetarium will include the new full-dome show "Two Small Pieces of Glass". Two students attending a local star party learn how the telescope has helped us understand our place in space and how telescopes continue to expand our understanding of the Universe. They learn about the history of the telescope and the discoveries these wonderful tools have made. The students see how telescopes work and how the largest observatories in the world use these instruments to explore the mysteries of the universe. Explore the Galilean Moons, Saturn's rings, and spiral structure of galaxies while learning about the discoveries of Galileo, Huygens, Newton, Hubble and many others. The show includes an interactive tour of our night sky including the current position and phase of the moon and the position of planets currently visible at night.
