‘ALIEN MEGASTRUCTURE’ The Universe’s Most Mysterious Star Gets Even Stranger

Astronomers have determined that there is something pretty amazing is going on around KIC 8462852 star. (The Universe’s Most Mysterious Star Gets Even Stranger)

Using a novel approach, astronomer Bradley E. Schaefer from Louisiana State University looked at a collection of sky photographs in the archives at Harvard College Observatory between 1890 and 1989 and measured 131 magnitudes of mysterious Star and concluded that he star appears to be dimming slowly, over the course of the past century; Specifically he determined that KIC 8462852 displays a secular dimming at an average rate of 0.164 magnitudes per century.

This century-long dimming is unprecedented for any main sequence star because usually, such stars remain very stable in brightness, with evolution making for changes only on time scales of many millions of years.

They found that the implication from dust-occultation ideas, Boyajian and Thompson calculate that the comet family scenario requires 648,000 giant-comets (each with 200 km diameter) to create the century-long fading, all orchestrated to pass in front of the star within the last century — this can be compared to the entire mass of the Kuiper Belt in our own Solar System. Schaefer says, “I do not see how it is possible for something like 648,000 giant-comets to exist around one star, nor to have their orbits orchestrated so as to all pass in front of the star within the last century.

So I take this century-long dimming as a strong argument against the comet-family hypothesis to explain the Kepler dips. The alien idea may make this seem silly, but the data are real. Something is going on around mysterious Star .” As Phil Plait, Slate’s Astronomy blogger added, “I don’t know what it might be, but what I can guarantee is that when we do figure it out, it’ll be something pretty amazing.”
