Kepler's 'Bizarre' Signal Sparks Alien Intelligence Speculation

The fascinating speculation surrounding a recent Kepler observation of a star 1,500 light-years away has reignited questions of alien life in our universe and what it means for future studies. ANALYSIS: Has Kepler Discovered an Alien Megastructure? First I really want to emphasize, as I did in my previous blog about KIC 8462852, that the root cause of a very strange Kepler transit signal is most likely due to natural phenomena. (A transit occurs when an exoplanet — or, in this case, something else — drifts in front of its star and Kepler detects a slight dimming of starlight.) After analyzing the unique transit signal identified as being “bizarre” by the Planet Hunters community, researchers did a thorough job identifying a possible mechanism by which significant and distinct dimming events could have been triggered.
