While talking of the universe, you simply cannot afford to miss Tabby’s star. Located around 1300 light years away from our earth in Cygnus constellation, the unusual peculiarity of the star has befuddled the scientist on a whole new level. Because of this aberration, It has been nicknamed WTF star meaning “where’s the flux star?”, highlighting the dips in the radiative flux.
The most bizarre thing about the star is its unusual flickering. It displays a huge drop in its flux which is around 22% whereas huge stars exhibit only 0.05% drop in their flux. Earlier, the protoplanetary disk was considered the reason behind this peculiarity, but later on it was discovered that this star is too old to have a protoplanetary disc and moreover it lacks the infrared flux emission that a star containing protoplanetary disc is supposed to have. There have been numerous hypotheses to decode its bizarreness, but all these efforts went in vain. Earlier the presence of cometary dust was thought to be the reason, but the fact that cometary dust gets blown off on the timescale of a month or two and it’s been centuries already since the behaviour of this star has been witnessed are substantial contradictions which cannot be overlooked. Another,One of the most popular hypothesis suggests this as an alien megastructure, basically a type 2 civilization trying to harness energy from star, constructing an apparatus that apparently blocks a large percentage of light, increasing the rate of blocked light periodically, but the phenomenon that any alien megastructure would be completely opaque thwarts this hypothesis.
To solve this mystery, over 19000 images has been taken over the past three years, in different wavelengths, where it was proved that blue light is always blocked in all events, again foreshadowing towards the dust, leading to the latest research suggesting that all this mayhem could be a result of the disintegrating exomoon. This planet may be exfoliating dust and lumps of rocks which apparently moves between us and tabby’s in a conjoing disc. As of now, this discovery seems to put a full stop on this real head scratcher phenomena.
