Alien Mega structure Can’t Be Explained by Comet Cluster

Back in October we reported on the weird “Alien Megastructure” that was seen close to the Milky Way.  KIC 8462852 star lies just above the Milky Way between the constellations Cygnus and Lyra. The most acceptable answer was that there was a cluster of Comets orbiting KIC 8462852 generating enough dust and debris to dim its light by up to 22%! Even so this theory is just as much a guess as the rest of the plausible ideas.

“Either one of our refutations has some hidden loophole, or some theorist needs to come up with some other proposal,” astronomer Bradley Schaefer from Louisiana State University told Jacob Aron at New Scientist.

When KIC 8462852’s bizarre light patterns were announced last year, the team behind the discovery offered up what scientists have considered the most plausible explanation.

When astronomer Tabetha Boyajian from Yale University and her colleagues first discovered that KIC 8462852 was giving off weird light patterns between 2009 and 2013, they checked 100 years worth of photographic plates held by the Harvard University archive to see if something similar had occurred around the star many years before. They come up with nothing.

Schaefer and his team from Louisiana State decided to check the data again using a different method of analysis, and noticed that the star dimmed very gradually by about 20 percent between 1890 and 1989. “The basic effect is small and not obvious,” he told New Scientist.

Schaefer concluded that for the star to dim by about 20 percent over the course of an entire century, it would require some 648,000 comets – each about 200 kilometres wide – to have transited KIC 8462852, and that’s completely implausible, he said. “The comet-family idea was reasonably put forth as the best of the proposals, even while acknowledging that they all were a poor lot. But now we have a refutation of the idea, and indeed, of all published ideas.”
