One of the biggest, most intriguing questions in the world is quite simple: Are we alone in this universe? Astronomer and astrobiologist Dr. Aomawa Shields looks for signs of life in outer space by analyzing the climate and habitability of small exoplanets far beyond our solar system.

Shields’ path to science was a winding one. Through childhood and into her adult years, she toggled between two loves: acting and space. In her new memoir Life On Other Planets: A Memoir of Finding My Place in the Universe, she describes her search for signs of life in the cosmos and her quest to build a meaningful life here on Earth. She charts her life story from childhood to astronomy to acting and back to science—and what she’s learned about herself and the universe along the way.

Guest host Swapna Krishna talks with Shields, professor at the University of California Irvine, about her research, the power that comes from combining the arts and science, and what she’s learned from pondering the universe.
