Astronomical (Non-) Trivia Contest

By Mark Moyer

We’ll explore a miscellaneous list of astronomical facts (about astronomical objects, amateur observing, astrophysics, the history of astronomy, and space flight). We’ll pose them as questions for a self-scored trivia contest, you can test your knowledge of astronomy or just have fun guessing the answers. The answers are not merely trivial factoids. Each one is chosen because an understanding of the answer gives us a deeper knowledge of some aspect of astronomy. Each question and answer will be followed up by an explanation that describes something significant about the heavens or our study of the heavens that will be both interesting and enlightening. So even if you join us just to listen in, you should find it fun and thought-provoking!

The Hertzsprung-Russell Diagram and Stellar Evolution

By Steve Quigley

Astronomy is a unique science.  With few exceptions, everything in Astronomy is based on light, and what information we can glean from it.  The Hertzsprung-Russell diagram is an excellent example of this.  This presentation will cover the techniques, events, and people who contributed to the development of the H-R diagram.  You’ll meet Germans, Italians, Danes, Indians, English, and American scientists whose work contributed to the “final” product.  Much of the action will take place at Harvard, and there you’ll be introduced to the “Harvard Computers.” This is a very basic summary of the work that led to the H-R diagram, and the insight it gives us into the concept of Stellar Evolution—the life and death of stars…… and all from understanding the message of the photons.
