The scientists were skeptical of discovering Star Death

NASA's infrared telescope discovered 7 light-years away from the Sun has a cold, small brown star that does not shine.

Is this a candidate for the role of Nemesis Death Star ? The name of the Greek revenge goddess is set for the hypothetical object causing the extinction of species on the ground periodically.

The story of the mysterious star appeared in 1984, when American archaeologists studied the corpses of ancient sea creatures that came to the conclusion that mass deaths of creatures on earth were repeated every 26 million years. Because that cycle is hard to explain with earthly causes, astronomical reasons are given. According to them, one of the stars near the Sun sometimes comes very close to the solar system. This causes a disturbance in the Oort Cloud - the field of billions of comets around the Solar System. Unbalanced, comets enter the solar system, causing "bombardment" battles on Earth and other planets.

People have been actively searching for the 'Death Star'. Leading researcher at the Institute of Astronomy Dmitry Vibe said:

'Occasionally appearing in science there are attempts to establish the frequency of changes in the geological conditions of the earth, climate, and the nature of the atmosphere. These efforts lead to a claim that there are 26 million years, or even longer. And people try to associate this cycle with some processes outside the solar system. One of the explanations for this is the presence of a distant star that accompanies the sun. This satellite rotates in orbit around the Sun for 26 million years. "

What did science know about the area around the sun? Four light-years away from the Sun has an Alpha Sentavra star system, and six light years away has Barnard star. Other "neighbors" have only been discovered in recent years, when processing giant data sets with infrared telescopes. For example, in 2013, the scientists learned about a "star heat" that only glows very little - "tiny stars" are evaluated as a "candidate" for the role of the death star Nemesis. And now its "brother" appears , but this is 'welding star'.

But then astronomers went into a dead end. To determine if this one object, "Nemesis" , it was necessary to know exactly how he moved to millions of years before CN. Calculate planet-like trajectories so that such time cannot be. It is possible that some objects are actually a satellite away from the Sun. Despite the fact that he led to the extinction of species on the ground.

While the debate continues, some astronomers suggest not to panic and give the project a more "peace" name - Tyche (Tyche). How did the Greek goddess of property.
