Polaris, the North Star, and the stars that shape the Big Dipper and the Little Dipper are fixtures in the sky of the Northern Hemisphere. To learn more how these and other stars are formed join University of Wisconsin-Barron County assistant professor Bradley Peterson for his presentation, “Smashing Galaxies, Building Stars,” December 14, noon to 1 p.m., in the Blue Hills Lecture Hall (R234). Peterson will introduce his research on star formation, describe how it occurs and how it is facilitated by collision of galaxies. His talk is part of the university’s Thursdays @ the U Performance and Lecture Series.
“While galaxy collisions are not uncommon today, they were even more common in the early universe, when galaxies were closer together,” Peterson said. “Understanding these collisions is an essential part of understanding why the universe looks the way it does today.” He also will discuss how different types of telescopes can provide varied and important insights into this process.
Peterson has taught physics and astronomy for the UW Colleges since 2012. He earned his Ph.D. in astrophysics from Iowa State University. He has also been a Visiting Graduate Student Fellow at the Infrared Processing and Analysis Center at Caltech.
Thursdays @ the U series is free and open to the public. UW-Barron County is located at 1800 College Dr., Rice Lake. For more information, call 715-234-8176.
