Mark your calendars for Monday, December 14th from 7:00 to 8:30 pm at the Fountain Hills Library for our first monthly meeting in quite a while. We’ll meet in the conference room just inside the Library. (This is the day before our next Library Skywatch, so please mark your calendars for that as well).
At this meeting we’ll meet and greet each other and I’ll give a couple of short presentations. The first will explain how we know the size of the universe. That story begins with the work of an amazing woman named Henrietta Leavitt who worked at the Harvard College Observatory from 1893 to 1912. She discovered an obscure class of variable stars whose changes in brightness provided the key to understanding the cosmic distance scale. Her work allowed Edwin Hubble to confirm that the universe was much larger than anyone thought at the time.
The second will be on “How to buy a telescope”, perhaps an appropriate topic just before Christmas! I’ll have examples of beginner telescopes that have proved easy to use and of sufficient quality to give good views.
Hope to see you there!
