Boyajian's Star (Tabby's Star) has mystified us since we first saw those bizarre dimmings recored by NASA's Kepler Mission. Over the years, people have shown that the data could be explained by comets, or planet engulfement, or even alien megastructures. But here at the Cool Worlds Lab, we had a different idea. Rather than propose a specific hypothesis and see how well it matches the data, why not use the data to reconstruct an image of whatever it was that caused the dimming? Sounds simple, right? Well it took us about two years to crack this damn problem but we're thrilled to finally discuss it with you all in this Cool Worlds exclusive!
