You’re invited to the next installment of the popular astronomy talks seried Dr. Knop Talks Astronomy. Here are the details:
Title: The Stars in a Galaxy
Date: Saturday, September 5, 2009 Time: 10:00 AM Pacific Time (SL Time)
Location: The large amphitheater on the sim named StellaNova SLURL: http://slurl.com/secondlife/StellaNova/213/210/32/
Abstract: We now know that most of the mass of a typical galaxy is Dark Matter. But, when you look at an image of a galaxy in optical or near-infrared light, the light you’re seeing comes from the stars. It turns out, however, that the stars that are responsible for most of the light you see are not representative! Most of the stars in a galaxy, and indeed most of the stellar mass of a galaxy, aren’t the ones emitting the light that you see in a typical image. In this talk, I’ll describe what we know about the kinds of stars that one finds in a typical galaxy. How typical is the Sun? What *are* the stars that we’re mostly seeing when we look at a galaxy? And what makes up most of the stars in a galaxy?
This science talk is intended for the general public. All are welcome. It’s part of a series of popular talks called Dr. Knop Talks Astronomy. Dr. Knop was on one of the teams that discovered the accelerating expansion of the universe.
Feel free to ask questions or make comments.
