KIC 8462852

It's been all over the news lately. KIC 8462852, an F-class star about 1500 light years away, is big news to its astronomy.

This is because of its erratic and strange luminosity curve, with two recorded major dips that extended up to 20% of its luminosity (for comparison, a Jupiter-sized gas giant would only take 1% of its luminosity.) Even more so, the star has been dimming for at least decades, at least up until the late 1800s.

There are two possibilities to this phenomenon:


  • Comets



A possibility is that disintegrating comets orbit elliptically around the star, which vary in size, although the evidence that the star has been dimming since the 1800s disproves this.


  • Aliens, of course.



This may sound ridiculous, but it's seriously what some scientists are straight up thinking. One possibility is that there may be an alien mega-structure or a Dyson swarm orbiting the star, however this explanation was ruled out after a survey by SETI, revealing no unique radio signals that may stand out.

Discuss.
