Tabetha Boyajian is best known for her research on KIC 8462852, a puzzling celestial body that has inspired otherwise sober scientists to brainstorm outlandish hypotheses.

Why you should listen

Planet hunter Tabetha Boyajian studies KIC 8462852 (dubbed "Tabby's star" after her team's research): a star exhibiting bizarre (and thus far unique) variations in brightness. These fluctuations have led scientists to postulate causes ranging from comet dust (Boyajian's most likely scenario) to alien megastructures. The latest studies of Tabby's star have proved even more baffling: KIC 8462852 has been gradually dimming over the last century, a strikingly short period of time on an astronomical scale.

Boyajian currently serves as 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.

The most mysterious star in the universe
13 minutes 36 seconds
Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.
