Kepler Telescope Discovered an Alien Megastructure

NASA's Kepler Space Telescope is tasked with finding small, rocky worlds orbiting distant stars. However, exoplanets aren’t the only thing Kepler can detect — stellar flares, star spots and dusty planetary rings can also pop up in the mission's observations.
But there's also been speculation that Kepler may have the ability to detect more than natural phenomena; if they're out there, Kepler may also detect the signature of artificial structures orbiting other stars.
