Part 3 of the TED Radio Hour episode Citizen Science.

About Tabetha Boyajian

Planet hunter Tabetha Boyajian studies KIC 8462852 (dubbed "Tabby's star"): a star exhibiting bizarre variations in brightness. These fluctuations have led to a host of theories ranging from comet dust to alien megastructures.

Boyajian is a postdoc with the Yale Exoplanet group, whose research is assisted by the Planet Hunters — a citizen science group that combs data from the NASA Kepler Space Mission for evidence of exoplanets and other unusual interstellar activity.
