Nasa shared photos of the first interstellar comets

As the portal, the Hubble space telescope space Agency NASA was able to provide scientists with data about the interstellar comet 2I/Borisov, whose speed and trajectory indicate that the visitor came to the Solar system from the depths of outer space. Why is this discovery so important to the scientific world and whether it can affect the development of modern science?

Comet, which came from the depths of the galaxy

In 2017, humanity first was able to detect interstellar visitor in our Solar system, which was the object “Oumuamua”flew 38.5 million kilometers from the Sun (for comparison, the closest planet mercury are from the Sun of approximately 58 million kilometres). While “Oumuamua” was the usual rock, 2I/Borisov is a full-fledged comet from another star system. Despite the fact that the alien wanderer is only the second in the history of mankind interstellar object that ever opened by astronomers, information about its structure can play an important role in the history of science. So, discovered the comet allows new insights to understand the structure, chemical composition and basic characteristics of dust in planetary building blocks that were formed by analogy with the material in the Solar system.

Comet 2I/Borisov moves in a hyperbolic trajectory around the Sun, passing over our star and gradually moving away from him. By mid 2020, the comet will pass Jupiter at a distance of 500 million miles on the way back to interstellar space, where it will sail a few million years, before you will be able to visit another star system. Their “turns” comet is doing tremendous speed, which is 177 thousand kilometers per hour. In order to photograph 2I/Borisov, the Hubble have to watch her as the photographer for a racehorse.

So far, all studied by astronomers, the comet was either out of the ring of icy debris surrounding the Solar system in the so-called Oort cloud or from the Kuiper belt, located beyond the orbit of Neptune. Scientists believe that the discovery of comet Borisov and Omwamwi the beginning of the era of discoveries of interstellar objects, to make periodic visits to our Solar system. According to the researchers, in the vicinity of the Sun constantly there are thousands of these travelers, although most of them are too weak to be detected by modern telescopes.
