Mysterious Star Baffles Scientists, Resurrects Alien Debate

Tabby's Star, also known as KIC 8462852, once again started the unusual pattern of dimming its lights, a behavior first observed in 2015. But KIC 8462852 hit the headlines when Wright and colleagues suggested that the star would be a good candidate to search for evidence of a large manufactured structure built by alien life. It can also tell scientists if an object is moving toward or away from the observer.

Efforts to explain the weird behavior of Tabby's Star range from the fanciful to the ho-hum - from the effect of swirling cometary fragments to a massive megastructure built by aliens.

Now, the star is repeating its fading act, according to Jason Wright, an astronomer at Pennsylvania State University. One astronomer thinks that a Dyson Sphere is causing the odd dips, thereby nicknaming Tabby's Star as the "alien megastructure" star. (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 star dimmed by up to 22 percent before returning to normal.

Cosmologists are sounding the cautions Friday as telescope perceptions distinguish irregular light examples originating from a removed star situated around 1,300 light-years from Earth in the heavenly body of Cygnus, in the external edges of the galaxy.

"It turns out there are lots of these dips in the star's light". "I think it's very likely that we haven't heard the right answer yet - that I haven't heard the right answer yet, anyway". The announcement of a new dip set off alarm bells in the astronomical community, and those with access to telescopes made plans to take spectrum readings.

After a period of inactivity, Twitter went into meltdown over the weekend after the star began dimming again.

Associate Professor Wright said that they need to have a team of people from other countries in the world that are ready to monitor and observe it. Stars tend to get dim when things like planets or even huge clouds of dust pass in front of them, but that kind of thing usually happens on a regular schedule, and only accounts for slight amounts of dimming.

"It's Super Bowl Sunday", Siemion said of the atmosphere at the during the webcast.

The astronomy world is going absolutely bonkers right now, and for good reason.

Yale University's Tabetha Boyajian, who led the research of the star and it is even dedicated to her for her work, said previous year that aliens could be responsible.
