Adam Frank on news that someone, some thing, somewhere, might be building a Death Star:
For the past week or two, the Internet has been lighting up about alien megastructures that might, or might not, be orbiting a star called KIC 8462852.
So what should we make of it? Is it just hype deserving a long, slow roll of the eyes? Or is there something in the story that deserves serious consideration?
If we do lots of exoplanet observations, then we are bound to see new things. For most of them, we will find “natural” explanations. But for some of them we may also need to, at least, consider the possibility of something more than natural.
The truth is still out there.
