Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to study particles coming from cosmic rays before they break up in the atmosphere.
