Charles Schweighauser, the first director of the James S. McDonnell Planetarium and Professor Emeritus of Astronomy/Physics, University of Illinois at Springfield, will highlight key astronomical discoveries that have taken place during the 50 years since the Planetarium opened in 1963. Professor Schweighauser will describe what we have learned about the electromagnetic spectrum and dark energy, the discovery of nearby extra-Solar system planets, the search for planets with conditions appropriate for life, and the dramatic evolution of astronomical practices.
