Dr. Wendy L. Freedman, John and Marion Sullivan University Professor in Astronomy and Astrophysics and the College, at The University of Chicago, describes the historical quest to measure how fast the universe is expanding. In 1929, Carnegie astronomer Edwin Hubble discovered that the universe is expanding and revolutionized our perspective on the cosmos. Decades of discovery followed. The launch of the Hubble Space Telescope (HST) in 1990 enabled astronomers to make measurements of the universe with unprecedented accuracy. The December 25, 2021, launch of the James Webb Space Telescope promises even greater precision. Dr. Freedman spent 30 years of her career at the Carnegie Observatories, 11 of those as director. She is best known for her measurement of the Hubble constant, which gives a measure of the size and the age of the universe. She will also describe how recent HST results suggest that there may be a missing piece in our current understanding of cosmology.
