I personally think there is a less alien explanation, but there is a report making the rounds today that scientists have detected a star, KIC 8462852, that experiences very unusual and erratic dips in brightness. The brightness change is around 22%, which is far more than typically observed from planetary transits, which is more like 1%, and are generally more consistent.
While there are probably a number of more rational explanations, astronomer Jason Wright, who specializes in signs of advanced civilizations, put forth the ideal that massive solar panels arranged in orbit, could be an explanation, although even he says we should “approach it skeptically.”
A Dyson Sphere, popularized and named after mathematician and theoretical physicist Freeman Dyson, is one of a number of theoretical megastructures in which a partial or complete shell is constructed around a star, allowing for near-complete use of the energy output of the star.
Another similar structure, the Ringworld as conceived by science fiction author Larry Niven, is a ring structure around a star where the inner surface would have millions of times the area of Earth as livable space. But in order to provide something approximating a day/night cycle on such a structure, a second, inner structure exists – the “shadow squares”, enormous panels in orbit that block the sunlight from the star from a section of the Ringworld.
Sound familiar? Perhaps we should be searching for Protectors or Puppeteers in the area…
