Two guest speakers for the fall Astronomy Education Workshop on Saturday, October 6th have been confirmed. Brian Thomas, an astrobiophysicist from Washburn University will be here to talk about dangers to life on Earth from space. His research specifically looks at how radiation events like supernovae and gamma-ray bursts will affect ocean Phytoplankton. Jeff Wilkerson from Luther College has extensive experience supervising undergraduate students on projects with small telescopes making photometric observations. Jeff will summarize his extensive program including a current major interest (development of rapid photometric techniques for the study of stellar signal variations) and describe how undergraduates benefit from these types of experiences.
