My guest today is Dr. Mary Voytek, the director of NASA's Astrobiology Program since 2008. Dr. Voytek and others from NASA are proposing a new 7-step framework on how they could report on the discovery of life beyond Earth. We'll discuss this new framework as well as the latest challenges in the search for life across the Universe.

My guest today is Dr. Boris Goncharov, a researcher at the Gran Sasso Science Institute. Boris is part of the team using the precise signals from pulsars as a way to detect gravitational waves. This technique could be sensitive enough to even detect merging supermassive black holes.
