The Mystery of Star KIC 8462852 Continues
Turns out, it's not comets.
Just when we thought there wasn't an alien megastructure circling star KIC 8462852, one researcher has stepped up to reignite our hope (kind of).
Last time we talked about the unknown structure circling the far-off star, scientists thought the cause for the light anomaly could be attributed to a swarm of comets.
“The scenario in which the dimming in the KIC 8462852 light curve were caused by the destruction of a family of comets remains the preferred explanation,” they wrote. However, they didn't rule out the possibility for an alien super-structure circling the star.
Researcher Bradley Schaefer has ruled out a family of comets as the cause for the dimming light seen in the star. He wrote in a recent paper that the light from KIC 8462852 has been fading for the last 100 years — a trend that couldn't be attributed to a swarm of comets blocking the star's light.
“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,” Schaefer concludes.
So, could it be an alien megastructure? Schaefer thinks not. He's doubtful that any alien species would have the resources to cover a fifth of a star. If they did, the structure should radiate some kind of heat signature.
As for an explanation to this strange dimming of light from star KIC 8462852, Schaefer has none. There's an explanation out there, it just requires more data to be uncovered.

Even some teachers suffer from anxiety about math.
I teach people how to teach math, and I've been working in this field for 30 years. Across those decades, I've met many people who suffer from varying degrees of math trauma – a form of debilitating mental shutdown when it comes to doing mathematics.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
The legacy of Felix Dzerzhinsky, who led Soviet secret police in the "Red Terror," still confounds Russia.
- Felix Dzerzhinsky led the Cheka, Soviet Union's first secret police.
- The Cheka was infamous for executing thousands during the Red Terror of 1918.
- The Cheka later became the KGB, the spy organization where Russia's President Putin served for years.
