Barely once in the overview of the telescope of the Crimean Amateur astronomer, an interstellar comet Borisov, first discovered in late August 2019, instantly became a “superstar” all the astronomical news of the world. The fact that the birthplace of the cosmic wanderer are not familiar to us around the Sun and a distant star system in the constellation Cassiopeia. However, it seems that the millennial flight of icy comets may be her last: the core of this giant “snowball” was already just about ready to fall apart, causing the comet to melt away with its passage past the Sun.
The Cosmic snowball, who arrived to us from the unimaginable depths of space, long time behaved, as befits behave normal interstellar comet. Leaving behind a bright trail of evaporating into the Universe of substance, the comet at breakneck speed and flew into the Solar system, straight rushing toward our star. But instead of quietly leave the neighborhood of our planet and fly away somewhere deep into our galaxy, the comet Borisov continues to be within the boundaries of the Solar system, in recent times saraas outbreaks of unknown origin, writes the portal .
Such strange behavior of the icy wanderer's scientists explain her possible death emergency. The fact that spewing during outbreaks more material, 2I/Borisov is slowly disintegrating, becoming less and less with every flash. In other words, may soon ignominiously end his existence, dispersed all his substance into the space surrounding it.
The fact that the comet Borisov came to us to “die” for the first time told the Polish researchers from the Jagiellonian University in Cracow, who managed to record the unusual activity on the comet. Scientists claim that the observed processes indicate ongoing fragmentation of the nucleus, that sooner or later will lead to its collapse. Anyway, such a sad event could be good news for earth experts. So, the death of the space traveler can tell about the internal structure of an object from another star system, as well as to tell about how often in our Universe substance-the ingredients of life.

One of the most important dates in the life history of comet Borisov was 8 December 2019, when the icy object reached perihelion — the nearest approach to the Sun. It is significant for the comet the earthly astronomers event allowed to find out the frequency 21/Borisov and determine the orbit of the comet.
To date, scientists distinguish only 2 types of comets, based on data about their frequency. So, short-period comets usually come from the Kuiper Belt — a kind of “nurseries” for many TRANS-Neptunian objects. Born in this dark and incredibly distant place, comets from the Kuiper belt make a complete revolution around the Sun approximately once every 200 years. This “belonging to his” protects comets, which are much more likely to remain intact during its passage past the Sun.

Long-period comets entering the territory of the Solar system is strictly prohibited: getting into gravitational trap of the Sun, the comet came to us from the depths of the galaxy, much more likely to disintegrate than, “neighborly” look at our place every couple hundred years. Analysis of colour and composition 2I/Borisov has shown that he is very similar to long-period comets, and therefore the decay heat from the Sun was expected, but not guaranteed.
In any case, astronomers will continue to closely monitor activity 2I / Borisova and, perhaps, in the near future, it is the comet, discovered last year, will be able to shed light on the origin of life in the Universe.
Meanwhile, earlier Hi-News.ru already wrote about the fact that some comets in the Solar system sometimes behave very strange. So, some of them can even “cliplets” each other like snowballs. The reasons for such a behavior space, you can read .
