In a galaxy, far, far away is a weird star called KIC 8462852 which has been confusing astronomers for decades and has decided to be weird again and has sent Astronomers scrambling to point their telescopes it's way.
The stars and planets act in a perfectly predictable fashion so there has been much head scratching as to why KIC 8462852, also known as Tabby's Star, changes brightness significantly and at irregular intervals.
Now there is another significant dimming dimming of the star 1,275 light years away in the Cygnus Constellation and the usual suspects such as a planet passing in front the star has been dismissed as this would not cause such a significant change in brightness, and it would be more predictable.
Other suggestions include a large, immensely dense cloud of dust and debris around the star or it is recovering having been hit by a planet and another theory suggests a swarm of comets may be responsible.
The whispered suggestion is that an alien mega structure has been built around the star to harvest its energy, something which is referred to as a Dyson Sphere, named after the man who put it forward as a theory in the 1960's as a way for future generations to power the Earth by partly enclosing the Sun with colossal solar panels.
It is a scary thought that if it does turn out to be an alien mega structure, and as were seeing how it was 1,275 years ago, while they had the intelligence and scientific know how to build a mega structure in Space, the 8th Century humans were inventing horseshoes and believed that a solar eclipse was the Sun being attacked by an evil demon.
Heaven help us if they ever discover us.
