How does studying Comet 67P/Churyumov–Gerasimenko start to shed light on some of the questions we have about the origins of the universe? For example, how did gas and dust form our solar system? How did we get from stardust to people? Are we alone in the universe or is there some form of life elsewhere?
Claudia Alexander, U.S. Project Scientist on the Rosetta Mission, and Cosmochemist at UCLA Edward Young explain how landing on a comet can help us validate or refute some of the current theories.
