TIL: That's No Moon. It's Aliens. (Maybe.) | Today I Learned

UPDATE: 11/6/2015 The SETI Institute reports that after observing the star with its Allen Telescope Array for more than two weeks, it has found no clear evidence for a signal in either narrowband transmissions, which might be used as a hailing signal for a society to announce its presence, or broadband signals, which could be "produced by intense microwaves used to propel rockets servicing the megastructure." (By the way, how clever is it that SETI has deduced how we might detect alien rockets in deep space? Pretty cool.) SETI hasn't given up, however. It continues to monitor the star, and scientists hope to use more powerful telescopes in the near future to listen even more closely.
