Jennifer Carter will discuss KIC 8462852, a star approximately 1,300 light years from Earth, which has been demonstrating a really-peculiar dimming signal. The star’s unusual brightness fluctuations were first observed by citizen scientists participating in the web-based Planet Hunters project. Follow-up observations by astronomer Tabetha Boyajian and others have eliminated many possible explanations. But one explanation still in the running is the possibility that these fluctuations are caused by a Dyson Swarm…a hypothetical megastructure constructed by exterritorial intelligence that would harness all or most of the energy from a host star to power an advanced civilization.
