To celebrate the release of Star Wars Rogue One this weekend, let's ask the question - could we detect the Death Star with our current telescopes? Remarkably astronomers have been thinking about the detectability of alien megastructures, such as the Death Star, for many years and we can apply some scientific thinking to get to the answer.
