The Art and History of the Night Sky
April 8, 2021
7:00 PM - 8:00 PM

Free online talk hosted by The Frick “The Art and History of the Night Sky” Thursday, April 8, 2021, 7:00 PM - 8:00 PM.

The night sky, whether full of stars or forebodingly dark, has been an inspiration for artists and writers for centuries. At the same time, illuminating the darkness has been a challenge taken on by humans as part of our attempts to master our environments and create new ones. In this program, we explore the historical and inspirational facets of the night sky through paintings, stories, and the history of Pittsburgh’s illumination in the 19th century.

Featuring: Dr. Elisabeth Roark, art history professor at Chatham University; Diane Turnshek, astronomy lecturer at Carnegie Mellon University and author of Triangulation: Dark Skies; and Dr. Joel Tarr, history professor at Carnegie Mellon University.

Lessons from the Universe

From Café Scientifique at Carnegie Science Center, listen to a talk by Andrew R. Zentner, a theoretical cosmologist and professor from the Department of Physics and Astronomy at the University of Pittsburgh. While we now understand the history of the Universe over the last 14 billion years in exquisite detail, there are still many valuable lessons that can be learned.

In his presentation, Andrew explored the possibilities for dark matter and dark energy, the formation and evolution of black holes, and the very early stages of the Universe which we inhabit.
