Lewis talks about the astronomical mysteries. Last year the media was abuzz with talk of Tabby's star, a pretty unremarkable F-type star in the constellation of Cygnus in the galaxy. The National Aeronautics and Space Administration's Kepler satellite found its light varied in a complex and unexpected way. Natural explanations were proposed, including a lumpy disc of orbiting material, the chaotic break-up of a planet, or clouds of comets. But the media latched onto one idea in particular, that the dimming could be due to "alien megastructures".
