Just a quick plug in case you missed it... BBC's Horizon programme has just aired an episode entitled 'Strange Signals from Outer Space!' which examines the (so far unsuccessful) search for extra-terrestrial intelligence (SETI). It finishes with a look at star KIC 8462852 (also known as Tabby's Star) where astronomers believe that there may be the beginnings (or remnants) of a Dyson Sphere.

If you aren't familiar with the concept of a Dyson Sphere (which is nothing to do with vacuum cleaners), it's worth reading hard-fiction novel Pandora's Star by Peter F. Hamilton whose story begins with an astronomer discovering a star that suddenly and mysteriously vanishes. It is the supposition of the scientific community that it has been encased in one of the aforementioned Dyson Spheres by a civilisation far more powerful than humans.

An exploratory mission to visit the star causes it's equally unexplained reappearance but this, in turn, leads to potentially devastating implications for the human race. It's the first book in a series (as all sci-fi novels seem to be these days) but it comes with the Wireless Waffle 'big thumbs up' seal of approval.
