Asteroids, Agnostic Biosignatures, & Experimental Rock Opera with Dr. Heather Graham

Подробнее о видео

Our guest is Dr. Heather Graham, organic geochemist and research associate from the NASA Goddard Space Flight Center. Dr. Graham's research focuses on the scientific development of tools and techniques that can help us identify “agnostic biosignatures” – evidence of living systems that may not share common biochemistry with life on Earth. Dr. Graham is also involved in studying the asteroid samples returned by the Hayabusa 2 mission. In addition to her work as an astrobiologist, she also co-wrote and directed an experimental rock opera about "Hidden Figures" Katherine Johnson, Mary Jackson, and Dorothy Vaughn, more than 2 years before Hollywood.

What is Ask An Astrobiologist?
Once a month, SAGANet (www.saganet.org) and the NASA Astrobiology Program host a program called "Ask an Astrobiologist", where the public is invited to interact with a high-profile astrobiologist, who replies to Twitter, Facebook, and chat questions live on video. Each session lasts about an hour.
