Several amateur astronomers, gazing at data from the Kepler telescope, discovered an odd flickering from one particular star, usually caused by objects in space passing in front of it. But that usually means the star is very young, and this one is not. In fact, the phenomenon is so strange in this case, that some scientists are considering some wild theories to explain it. Could we be witnessing an alien super structure? Jeff and Anthony talk through all of the wildest ideas and decide if they's aliens.
