That star's 'alien megastructure' is likely just a swarm of comets
Occam's Razor apparently holds true everywhere, even in the farthest reaches of space. While researchers speculated that star KIC 8462852's mysterious dimming might be the result of alien megastructures, NASA is about to publish evidence supporting the theory that it's really just a swarm of comets. Based on the strange dimming and the moderate infrared light levels, you may be looking at a pack of cold comets on a "very long, eccentric" orbit. If so, the strange signatures over the years reflect different-size comets passing around the star.
