Cosmology Q&A with Wendy Freedman

Why do we think dark energy exists? And what will supernovae tell us about the fate of the universe? One of the world's leading cosmological observers explains.
Astronomer Wendy Freedman works on the forefront of observational cosmology: the use of telescopes and other instruments to study the origin, structure, evolution, and fate of the universe. Born in 1957, Freedman is a native of Toronto, Canada. She received her Ph.D. in astronomy and astrophysics from the University of Toronto. In 1984, she joined the Carnegie Observatories in Pasadena, California, as a postdoctoral researcher. A permanent staff position followed in 1987. And in 2003, Freedman became director of Carnegie Observatories.
