Dr. Kris Stanek of Ohio State is in Louisville today to give the annual Bullitt Lecture in Astronomy at the University of Louisville. His professional work involves the study of supernovae, gamma-ray bursts, very massive stars, and cosmology.

This afternoon on Here and Now, Dr. Stanek spoke with WFPL’s Jonathan Bastian about how scientists through the ages have gone about measuring the size and age of the universe.

His Bullitt Lecture takes place tonight (Oct. 11) at 7pm in the planetarium on campus. Non-scientists are more than welcome, and the lecture is also child-friendly (10 years and up).
