SOUTHERN MAINE ASTRONOMERS MONTHLY MEETING Date: Thursday, May 2, 2019 Time: 7:00 p.m. Location: Southworth Planetarium Free and open to the Public Topic: *An Introduction to Radio Astronomy * *Presenter: Jon Wallace* Are you aware that most of what we know about the universe was learned using radio telescopes? We will explore the uses that astronomers are making of radio astronomy and the advantages of radio versus optical observing. Since radio picks up lower energy (lower temperature) objects than optical astronomy, we can use radio telescopes to look at very different objects. A demonstration radio telescope will be used before the presentation to give a hands-on experience to participants. All are welcome! Doors open at 6:30 p.m. www.southermaineastronomers.org
