Observatories around the world received a message stating that the star KIC 8462852 again reduced brightness. This allowed scientists to explore the star, which puzzled everyone back in 2015. The fact is that, from time to time, she was noted to have different degrees of brightness, which in no way could be attributed to the passing planet. At a certain point, a 22% drop was noted.
Not surprisingly, a huge array of assumptions has been formed. Some included comets, a gas cloud, or an alien structure. But none had a solid evidence base. Scientists could only wait for re-events. And the best option is to use all the observation tools to study the spectra. For example, if it were a gas cloud, you can understand how it affects the light and even study the chemical composition of gases. But this is difficult to do, since the blackout events do not have the nature of periodicity. They are unpredictable and should only rely on luck. That is why the whole scientific community was activated when it happened again. Now all terrestrial astronomers have received a message and note a drop in brightness on Tabby. As soon as all this is over, we hope to get new interesting information that will contribute to the disclosure of this mystery.
