REMINDER!
 
Dr. Robert A. Benjamin of the University of Wisconsin-Whitewater, will give a free public lecture on Friday, 5 October, at 7:30 p.m., in the Koury Auditorium at the Jamestown campus of Guilford Technical Community College.  (Note that this is a different building from the site of TriStar).
 
A Visitor’s Guide to the Milky Way Galaxy
Determining what our Milky Way Galaxy would look like from the outside is one of the great unfinished projects of astronomy. In this talk, I will review the history of the efforts to determine the structure of our own Milky Way Galaxy, starting with the star count maps of William and Caroline Herschel in 1785 and ending with the discovery of a new section of spiral arm on the far side of the Milky Way in 2011. I'll explain why mapping the Galaxy is hard, discuss the current picture, and point out what things are almost certainly true, and what things may yet change as techniques and telescopes improve.
 
Bob Benjamin is a professor of physics and astronomy at the University of Wisconsin-Whitewater. His recent work has focused on the structure of the Milky Way Galaxy, using the Spitzer Space Telescope to map the distribution of stars throughout the disk of the Galaxy. He has also worked on the interstellar gas in the Milky Way, developing models of intergalactic gas clouds and galactic "fountains" of gas. He obtained his PhD at the University of Texas at Austin, with postdocs at the University of Minnesota and University of Wisconsin. We are honored to have him as the latest Fall Astronomy Day speaker at GTCC.
