The Sun is the star of our planetary system, which actually gave life to it, therefore it is quite important to monitor what is happening on it, studying the possible consequences for our future. Actually, this is why many experts put forward varying degrees of verity of the theory about what happens to the star, based on observations from the Earth through telescopes, as well as sending automatic spacecraft to the distance as close as possible to the celestial body.
In particular, quite recently interesting information has appeared: the Sun is gradually beginning to reduce its magnetic activity. In recent years, it has become a record low, in connection with which it can be noted that the bowels of the luminary began to work differently, in a completely different mode. As noted by the astronomer Ivanna Ellsworth, an employee of the University of Birmingham, for the current cycle, which began in 2008, the star continues to behave differently than before, and this is generally the longest period of such a drop. Actually, the conditional activity is determined by flares and spots - they study how many of them there are.
For the specified time, respectively, they appeared at a minimum. What this will lead to is not yet clear. Some experts say that "the aliens are to blame for everything", who decided to derive some benefit from our star, while others are more careful in their judgments, saying that more should be observed. In theory, this could just be a sign of the aging of the Sun. In addition to direct activity, experts are also interested in other phenomena of our star. For example, a team that included American and Norwegian scientists built a visual mock-up that explains how spicules appear - pillars that represent luminous plasma. Their length is 20 thousand kilometers, and their thickness is a couple of hundred, they arise in huge numbers, but they are not long-livers: the maximum life span is only 10 minutes.
Experts who observed them described them as grass burning on the prairie. Actually, even though specialists had an idea about the spicules themselves several centuries ago, the mechanism of their occurrence was not clear. Computer simulation in modern times did not give the expected results for a long time. Juan Martinez-Sikora, the lead author of the study of the functional of spicules, noted that most often the magnetic field is related to charged particles. Nevertheless, when only they were used in experiments, nothing worked: the spicules did not break through to the surface, for some reason they simply got stuck. It turned out differently, when specialists on a computer model used a certain amount of neutral particles. Thanks to them, the swirling magnetic energy nodes became more "buoyant" and still crossed the chromosphere,breaking through the level of boiling plasma. The outer shell is just characterized there by "snapping" into spicules, and ions and neutral particles rub in such a way that everything heats up as much as possible in both the outer and inner balls.

It is also curious that a second star could have existed in our planetary system earlier. Rumors about the luminary, which was given the code name Nemesis, have been circulating for a long time, but until recently they were quite unsubstantiated. Now, when they analyzed the radio wave radiation from the dust cloud, which is about 600 light-years away from us, information has appeared that the star really was. This celestial body was characterized by relative dimness, therefore it was difficult to determine even its former existence.
When exactly she disappeared and where she went, it is also not known, however, it is believed that the "second sun" influenced the disappearance of various creatures on our planet more than the alleged and accused comets and asteroids. Experts have monitored what is happening in the constellation Perseus, investigating how many there are double and "ordinary" stars. In fact, the latter were 45, and the first - 19. There were also such planetary systems where several stars coexisted together at once.
At the same time, it could be noted about binary stars that they are not so many, as by the standards of space, years - only half a million or even less. At the same time, they are slightly removed from each other, while several old luminaries approach slightly. According to statistical models, the distribution of all the stars in the dust cloud of the constellation Perseus in this way could be so precisely because they once had a twin star.
Although rather distant objects were considered in fact, experts think that this may indicate the same processes in our planetary system. In the end, the Universe has clear laws of its existence, and if something is fixed somewhere, then with a high degree of probability it also happens in another place. And in general, there are a huge number of double stars, even within our Milky Way, at least half of the "suns" are such.
Meanwhile, our planetary system after about one and a half billion years can be seriously damaged, as has already been proven. The sun warms up more, will emit more radioactive radiation, because of which the Earth, in particular, will simply burn out, and the water will evaporate. It is likely that mankind should seriously think in the coming centuries about how to come up with a way to move not only to nearby Mars, but somewhere else to another system. In this regard, the problem of finding suitable planets for life is not yet acute, but the development of technologies in this direction can be attributed to the conditionally priority for the future of mankind.
