Space-time is big, both in size, the number of objects (exoplanets, stars, galaxies, etc) in it, and its 13.8 billion year age. Our daily lives don't prepare us to comprehend these astronomical quantities. We can see about 5000 stars from a non-light polluted area. A small amateur telescope will show us millions of objects, and professional telescopes have cataloged billions of objects. Andover resident, Brewster LaMacchia, public outreach coordinator for the North Shore Amateur Astronomy club, will offer some perspective on what can be seen with a telescope and how we categorize objects in ways to improve our understanding of our universe. MHL has 2 telescopes to lend at https://mhl.org/library-of-things.
Due to the predicted heat wave, Memorial Hall Library will be open Friday & Saturday, 9am-9pm & Sunday, 9am-5pm.
