Most scientists, including Wright and Boyajian, don't think it's very likely that there is an alien civilization building planet-size structures around one of their stars. To find out, scientists are looking at the spectrums of light coming from Tabby's Star, because light is manipulated as it travels through different things, like expansive bodies of gas or hot cosmic dust.
But KIC 8462852 has been experiencing erratic dips of up to 22 percent, and there's no periodic orbiting going on here - just a bunch of irregular, light-blocking shapes, with no discernible pattern to them.
The star that has been the focus of theories about alien megastructures to explain the unknown source of the light fluctuations first observed in 2009 is now in everyone's telescopes, as astronomers and astrophysicists try to figure out the puzzle.
"We're still quite unsure if it is, in fact, a duplicate of that event, meaning that it's the same object that's passing in front of (the star)". It has bewildered cosmologists from that point forward, however this is the first occasion when they've seen it diminishing continuously, displaying an unprecedented chance to watch whatever it is that is hindering the star's light.
Tabby's Star is mysteriously dimming again as reported by Fairborn Observatory in Arizona. So we need to have a network of people around the world'.
What's weird about the star is that it goes through dramatic and somewhat random periods of getting dimmer from our viewing perspective here on Earth. The largest and most powerful telescopes that will heed the call are the twin 10-meter telescopes at the W.H. Keck Observatory in Hawaii. Indeed, something was up this past weekend, as one of the Universe's most mysterious stars reignited some baffling behavior. This can be a challenge due to the way that telescope time is proportioned. (Dips detected by Kepler lasted for between two and seven days, according to Wright.) Professional-grade telescopes typically schedule observing time weeks or months in advance, so Wright and his colleagues knew their observations would have to come at the behest of colleagues who were already using the telescopes for other projects.
The SETI Institute's initial radio reconnaissance of the star, however, found no evidence of technology-related radio signals from the star.
