Are we alone in the universe? NASA's exploration of TRAPPIST-1 has the potential to answer one of humanity's deepest questions.
When NASA announced the discovery of the TRAPPIST-1 solar system in February 2017, humanity’s collective ears spiked. The system is made up of a dwarf star surrounded by seven "Earth-like" exoplanets at potentially habitable temperatures. If we want to know whether we’re alone in the universe or if we have company, the exploration of this planetary group may get us closer to an answer. Bill Nye explains some key signals NASA’s researchers will be looking for as they focus their intellect, and telescopes, towards this extraordinary next step in our history. Unstoppable: Harnessing Science to Change the World.
