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 reach as close to the top of the atmosphere as possible. The instruments in the balloons can then record the particles coming from cosmic rays before they break up in the atmosphere. Dr. Seo further explains how her work can help humans understand the origins of cosmic rays and why they are so highly energetic.
