Discovered more than 2 years ago a star in the constellation Cygnus is characterized by unusual and irregular changes in brightness, which reached up to 20% of the Researchers do not know whether this mysterious phenomenon may be related to orbiting around a star cloud of dust, or whether we are dealing with the installation of advanced extraterrestrial civilization.
Meanwhile, astronomers report that identified just another star, who has been seen even larger declines.
Is there a Dyson Sphere? This hypothetical mega structure described by American physicist and a range of world-renowned Freeman Dyson in “Science”. As we read in Wikipedia: “in accordance with the provisions of the author accordingly advanced civilization would be able to build a massive construction that completely surround the star, allowing the use of almost all the energy radiated by a star for the purposes of civilization”.
Let’s start with the fact that watching the distant star you can see very small dips in brightness. When it comes to transit exoplanets in the background shield stars, its luminosity may fall by up to 1% in the case of KIC 8462852 brightness declines are up to 20%, which indicates that a large object can simply block this star.
Unable yet to solve this puzzle, and now we have another on his head.
The EPIC 204278916 is a star, which was discovered in 2014, with the cosmic Telescope Kepler. This star has a size similar to our Sun, but its mass is less about half. The researchers conducted observations of celestial body by nearly 79 days and made a startling discovery, irregular brightness declines were even 65%.
Experts are of course more than one explanation for this phenomenon.
The first proposal is talking about a massive swarm of comets, and according to the other, the star can rotate with such great speed that comes to her flattened at the Poles, there are higher temperatures and the equator is duly obfuscated. Less plausible explanation, which, however, has not been rejected, says about the so-called Dyson sphere-a hypothetical mega-structure, described nearly 60 years ago by Freeman Dyson. This is an installation that would surround a star in order to collect energy for, respectively an advanced civilization.
So we have two interesting celebrities to explore. Astronomers will lead the subsequent observations of these objects to explain whether the stars are simply obscured by space debris, or whether we are dealing with something more unusual.
