New data is in on mystery star’s recent weirdness
We are not saying that these are unknown, but it can not be said that these are certainly not strangers.
At the end of last week, astronomers around the world are prepared to work over the weekend by watching one of the most enigmatic stars known to mankind: CCI 8.462.852, better known as the Star Tabby The Boyajian star or the “star of foreign mega structures”. Amateur observers and pro-star telescopes trained in the star about 1,400 light years away, and now we can look at these comments and take some careful steps and attempts to solve the mystery of this very strange star.
The alert expired on Friday that strange cracks in the brightness of the star first discovered in Kepler’s data by a crowdsourcing effort were produced once again – these still hollow has explained, resulting in all sorts of theories, ideas Like enormous geometries built by an advanced extraterrestrial civilization. The astrophysicist Tabetha Boyajian, who led the public science project and is called the star, predicted last year that the brightness of the star could be recast in May 2017.
When its prediction began to materialize last week, large observatories and amateur astronomy groups were notified through social media and other channels, and many have swung their lenses towards the constellation Cygnus and the mysterious star.
The best places in the space for the search of extraterrestrial life
What makes this star so strange is that it does not seem like its scans in the brightness to follow the obvious patterns. When planets or even comets pass in front of their stars, they tend to occur at regular and predictable intervals and usually block the same amount of light from a star as the last time they made a pass. But immersions observed in the brightness of KIC 8462852 do not happen in a very tight schedule and they vary in the way in which they reduce the light of the star: three to more of 20%.
To make matters even stranger, the old observations of the star show that it also declined slowly during the last century. Therefore, in addition to these strange short-term falls when something looks beyond the star, it also becomes much less clear in the long run, as if someone spilled their energy output as you would with their lights Of the room using a dimmer. We do not see many other stars behaving this way, if need be.
So back to the last observations: on May 19, in the light of KIC 8462853 fell almost 3 percent over a period of approximately 24 hours. This is according to new data from the California Summits Observatory that Boyajian discussed with Columbia University scientist David Kipping in the video recorded live on Sunday.
On Monday morning, astronomer Jason Wright (who was the first to propose the idea that foreign mégastuctures could explain unpredictable dives) noted that the soaking seemed finished and the star returns to its normal brightness.
It turns out that the drop observed over the weekend is somewhat similar to a 3 percent decrease seen by the Kepler space telescope a few years earlier, which leads Boyajian and others to wonder if this could repeat or follow a different type of model after all.
