As expected, those who have been in the field a while are advising against jumping to conclusions:

‘Aliens should always be the very last hypothesis you consider,’ Penn State astronomer Jason Wright told The Atlantic, ‘but this looked like something you would expect an alien civilization to build.’

One theory for an advanced alien race is that they might harness the power of an entire star, known as a Dyson Sphere. However, if such a structure existed, it is theorised that we would be able to detect its infrared signature – but a recent study found no such evidence.

This is one of the more fascinating space stories of the year.  I would expect that they focus more on star KIC 8462852 and will keep everyone updated!
