Astronomers may have found giant alien 'megastructures' orbiting star near the Milky Way | World | News | The Independent
1480 light years away, between Cygnus and Lyrae. ~20% of the light from this star gets blocked out for periods ranging from 5 to 80 days. Considering that large planets typically only block out around 1%, whatever is doing this is almost certainly not a planet. I'm also pretty sure that a planet that large would cause a significant wobble on the host star that would've been detected already.
So it's either a huge family of comet or planet fragments in an irregular elliptical orbit, or ET and his buddies are part way done building a Dyson Sphere (technically, this was 1480 years ago, so "were part way done" would be more accurate).
The latter scenario is both awesome and kinda terrifying to think about.
