The Triad Starfest, *Tri*Star*

Saturday 7 March 2015

Sears Applied
Technologies Center

Guilford Technical Community College

Jamestown, NC

The next edition of TriStar is tentatively scheduled for 4-5 March 2016.
Details will be posted later.

The Triad Starfest, *Tri*Star* for short, is a gathering of astronomers of all types, from novice to professional, for a full day of presentations, displays, and observing. The event allows astronomy enthusiasts to share ideas, learn about a range of astronomical topics, get together with old friends, and make new ones. The event will draw astronomers from North Carolina and surrounding states.

*Tri*Star* 2015 was held on Saturday, 7 March 2015, beginning at  8:30 a.m. in the Percy H. Sears Applied Technologies Center on the campus of Guilford Technical Community College in Jamestown, NC.  NOTE – the next edition of *Tri*Star* will be held on 4-5 March 2016.  Watch for updates in late 2015.

In addition to a series of speakers scheduled throughout the day, there will be a wide range of astronomical displays, assorted astronomy-related vendors, prize drawings, “how-to” help for astronomy beginners, an astrophotography exhibition, and daytime and nighttime observing sessions (weather permitting).

In addition to Saturday’s agenda, *Tri*Star* usually features a special Friday evening presentation held in the Auditorium of the Sears Building (the same location as Saturday’s activities), at 7:00 p.m., with Cline Observatory open for observing after the talk, weather permitting.  This year’s featured speaker is Dr. Tom Brown of the Space Telescope Science Institute.

Best of all, there is no registration fee – this event is free and open to anyone with an interest in astronomy!

Note: In case inclement weather causes the Jamestown Campus of GTCC to be closed on the date of *Tri*Star*, please monitor campus status before coming to GTCC. Information is available at the GTCC web page, on Twitter, or by dialing the GTCC switchboard at 336-334-4822.

Pre-*Tri*Star* 2015 Public Lecture

Auditorium, Applied Technologies Building, GTCC

Dr. Tom Brown, Space Telescope Science Institute
Deepest Hubble Images Expose the Violent History of our Galactic Neighborhood

About the Talk: As the other giant galaxy in the galactic neighborhood, the Andromeda Galaxy offers an invaluable laboratory for understanding the formation and evolution of spiral galaxies. Using the Hubble Space Telescope, we obtained six deep images of Andromeda, including the deepest optical image of space ever obtained. By imaging stars over an enormous luminosity range, these data allow a complete reconstruction of the star-formation histories along various sight-lines through the galaxy. The data demonstrate that Andromeda has suffered a more violent history than our own Milky Way. These deep fields subsequently became the baseline for measurements of Andromeda’s motion, revealing how it will eventually collide with the Milky Way, in the most spectacular merger yet.

About the Speaker: Tom Brown is an astrophysicist at the Space Telescope Science Institute, spending half of his time doing research and half of his time supporting NASA missions. After completing his studies at Penn State and Johns Hopkins, he worked for five years at NASA’s Goddard Space Flight Center. In 2001, he became an Instrument Scientist at the Space Telescope Science Institute, supporting two different instruments on the Hubble Space Telescope. Since 2008, he has been STScI’s Mission Scientist for the James Webb Space Telescope, while continuing to perform research using Hubble. To date, he has been the principal investigator for over a dozen Hubble projects focusing on star and galaxy formation in the nearby universe.
