The Weirdest Star In The Sky Is Acting Up Again
If a distant sun was surrounded by a swarm of solar panels built to cater for an advanced extraterrestrial civilization, at first it may seem a little tabby stars.
The strange celestial object, located about 1,300 light years from Earth in the constellation of Cygnus, behaves unlike all the stars never seen scientific. Several years ago, researchers working on the Kepler space telescope noticed a yellow-white dwarf star named KIC 8462852 shimmering like a ditch sail. From time to time, and for no reason could detect the brightness is granted up to 22 percent.
In 2015, Yale University astronomer Tabetha Boyajian published an article evaluating possible explanations for the attenuation effect, but none appeared to be adapted. The gradation was much more irregular and dramatic than could be caused by a planet passing in front of the star – even a gaseous giant like Jupiter blocks only 1 percent of sunlight. Other natural explanations, like a group of comets that swarm around the star, do not match the data of what became “Tabby Star” for Boyajian.
Jason Wright, an astronomer at Pennsylvania State University involved in the SETI (Search for Extraterrestrial Life) has proposed an unnatural explanation: a swarm of mega foreign structures. Darkening has more or less matched what scientists might expect to see a Dyson sphere – a giant solar panel system that an advanced extraterrestrial civilization could hypothetically use to harness the energy of a star.
“Never has extraterrestrials” is a rule rather than honor in astronomy. The history of science is riddled with examples of phenomena that resemble the signs of strangers, but turned out to be much more mundane. And Wright admits he does not have the extraterrestrial intelligence to make a star behave strangely.
But the very unlikely possibility that something is out there means that astronomers can not stop talking about the star of Tabby. And, whatever the source, you have to understand the gradation.
Therefore, when the celestial object began to blink last week, Wright Boyajian and the rest of the astronomical community were lightly bananas.
Although a series of gradation events are documented in the Kepler space telescope data was the first opportunity for researchers to see the Tabby star flicker in real time.
This is a big problem as it means that scientists can identify the star with a series of telescopes that operate in a variety of ranges across the spectrum. This will allow them to take spectra, that is, analysis of the wavelengths of light emitted by the star to understand what a fact is and what is blocking its light.
These data will be crucial to identify the origin of the strange behavior of the star of Tabby. For example, if a swarm of comets disintegration causes gradation, they will be very hot and close to the star, and scientists can see in the infrared part of the spectrum, according to the Verge. Good quality spectra could also help prove the theory that the star is erratically devouring a planet the size of Jupiter.
Boyajian had previously predicted that the star could happen again in May, and this month, it has been rightly proven. On May 19, the light Tabby star fell to 3% over a period of approximately 24 hours, Boyajian reported on a live transmission Q and A. Now returns to normal.
“It looks like the dive was over,” said astronomical epineur David Kipping of Columbia University in the journal Science. “But … in Kepler’s data, we saw multiple episode cracks cluster a few weeks.” So far, this pattern of behavior is similar to the events detected by Kepler, according to scientists, it is possible that the attenuation is caused by a single object through several times before the star.
