Sept. 5: Dr. Knop Talks Astronomy
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.

MICA Popular Talk - Black Holes, Bright Lights: Quasars as Probes of the Early Universe
Speaker: George Djorgovski (RL) / Curious George (SL)
Date: Saturday, March 21, 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: Quasars are the most powerful sources in the universe, believed to be powered by accretion of matter onto supermassive black holes in the cores of galaxies. Their formation and evolution likely traced the formation of galaxies themselves. Due to their brightness, they can be seen at very large distances, reaching to the times when the universe was less than a billion years old. They can be used to illuminate the early stages of evolution of galaxies, large scale structure, and the intergalactic medium.

Seminar: “Galaxies in Collision”
You’re invited to a free public astronomy seminar in Second Life. Here are the details:
Dr. Knop Talks Astronomy Title: “Galaxies in Collision”
Date: Saturday, October 25, 2008
Time: 10:00 AM Pacific Time (SL Time)
Abstract: Stars within a galaxy like our own almost never collide with each other. Galaxies themselves, however, run into each other all the time. What’s more, when the Universe was younger and smaller, they ran into each other more often. In this talk, I’ll give an overview of the sorts of things we see observationally when galaxies run into each other, causing not only the beautiful cosmic collisions that we’ve seen images of, but also triggering huge bursts of star formation and even tremendous activity at the nucleus of those galaxies. All are welcome. Feel free to ask questions or make comments.
