Earth's Moon: How it Came to Be and Why We Have Solar and Lunar Eclipses. In this 30 minute presentation, with North Shore Amateur Astronomy Club's Justin Murray, and Star Party Coordinator, Brewster LaMacchia,  we'll start with a look at the event 4.5 billion years ago, referred to as the Big Splat, that led to the formation of Earth's moon.  Using a variety of simple models we'll develop an intuitive understanding about the moon's orbit around Earth, moon phases, and what it takes for eclipses to happen.  After the presentation we'll head outside to look through telescopes provided by volunteers from the NSAAC.

Best for ages 10 and up. No registration required. In the case of rain/cloudy weather the star gazing portion of the evening will be postponed till April 16 at 7:30pm.
