📄𝗧𝗿𝗮𝗻𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
In 2015, an American astronomer Tabetha Boyajian discovered a new star 1,470 light-years from Earth. Besides its official name it’s also known as Tabby's star, Boyajian's star, and WTF star, where, in this case, WTF stands for “where's the flux”.

What makes the star special is that it displays unusual light fluctuations, unlike any that have been seen before. It was thought at first that the star might have a large planet which, from time to time, blocked some of the light as it passed between the star and Earth. But, normally, when exoplanets do this they dim a star’s light by only a small amount – about 1 percent or less – and at regular intervals. In the case of Tabby's star the fluctuations are up to 22 percent and irregular. Also, if Tabby's star had a large planet, it would appear to wobble because of the planet’s gravitational pull. However, no such wobbling has been detected.

Things got more interesting when some researchers suggested that the light fluctuations might be caused by a Dyson sphere. Simply put, a Dyson sphere is a hypothetical mega-structure that completely surrounds a star and captures almost all of the energy that it radiates. If there were a Dyson sphere around Tabby’s Star, the erratic fluctuations of light could be explained. It would be an extraordinary discovery and proof that we’re not alone and that at least one advanced alien race is out there.

In 2017, new studies and further analysis showed that when Tabby's Star dims, some wavelengths are blocked more than others. If there were a Dyson sphere around the star, it would be expected to block all wavelengths equally.

Scientists now think that the most plausible explanation for the strange light variations is the presence of some sort of dust cloud or a swarm of comets in eccentric orbits. The problem is: there would have to be a huge amount of dust or comets. Where could all that material come from?

One possibility is a disintegrating exomoon. A moon might have become separated from its planet and then broken apart, shedding dust and debris into a gigantic cloud, which, because of its clumpy nature, causes random fluctuations in the starlight we receive.

Another possibility is that Tabby’s Star is really a binary system. In 2021, astronomers found that Tabby’s Star may have a stellar companion – a red dwarf. The combined gravitational pull of the two stars could cause planets and other orbiting bodies to be torn apart into clouds of debris.

While we have various plausible theories, the behavior of Tabby’s Star remains a mystery – one of many in a universe full of surprises and strange phenomena.
