Re: Weird lights, might be aliens (KIC 8462852)
Astronomers have been watching Tabby's Star, and they've said that when, or if, it dims again, they will analyze its light with the spectroscope. By this they expect to determine if dust, or something larger is causing the star to dim.
With Dr. Schaefer's recent findings, we see that the star had been continuously dimming, over the century 1890 to 1989. We see indications in the current magnitude of the star that this trend has continued to this day.
If this is so, then the spectral studies already done of this star, which failed to find excess dust, seem to show us that larger objects are responsible for the dimming of KIC 8462852.
So, how large might the objects be? We see that the star has been dimmed up to 15 to 22 percent.
This suggests that something is covering about 40 to 50 percent of the star. This amounts to some 550,000 to 700,000 miles.
Natural objects of this size are stars, not planets. It seems natural to expect that they would shine conspicuously. No such stars have been found near Tabby's Star. The searches have been sensitive enough to find a distant red dwarf companion star.
Assemblies of solar collecting structures? The more we learn, the less improbable this seems.
