Our planet's precious metals such as gold and silver prefer to meet together. For a long time it was believed that the space they are friends - both produce the same star. However, the work of the German astrophysics Camilla Hansen showed that it is not. Silver is born in the explosion of one of the stars, and the gold is very different.

According to the most common at the moment, the version about the appearance of heavy metals in the Universe, these elements are born in the depths of light. The calculations show that due to the extreme pressure and tremendous temperature inside them begin leaking nuclear fusion reaction. It all starts with elementary transformation of nuclei of hydrogen in such helium, however, after the massive stars begin and more interesting things.

Thus, under the influence of the enormous gravity of temperature and pressure inside the star kernel simplest elements are so close to running around free alpha particles (helium nuclei)and protons, neutrons (their source is the reaction of compound nuclei of the isotope 12C to education in one case, 23Na, and the other 23Mg). At some point they even begin to connect to each other - and this despite the electrostatic repulsion of the charged charges. As a result, such kernel "acquire" new particles that leads to the appearence of heavy chemical elements from carbon, nitrogen, oxygen, phosphorus up of iron, lead and uranium.

Thus, it turns out that almost the entire periodic table in the evolution of the Universe has created exactly the luminaries of the source of the quark-puhovoi plasma occurred only the whirlpool, helium and so maybe Li. According to the models of scientists, which will create a star depends on its mass. It is believed that the most difficult obtained by supernova explosions most massive stars. Such glowing "fat fellows" and give rise to most precious metals for humanity - silver and gold.

On this basis, for a long time scientists thought these two noble element can be generated one star, or at least luminaries one "weight" category. However, a recent study by Dr. Camilla Hansen of the University of Heidelberg have shown that it is not. It found that silver appears only as a result of explosion of certain types of stars that are very different from those that "make" in gold.

Astrophysicist reviewed numerous reports of supernova explosions, after which showed traces of silver. Surprisingly, gold there practically was not. The similar picture was observed in the opposite case - the "Golden" supernova did not give a significant silver race". From that Ms. Hansen made a logical conclusion - the production of these metals will likely depend not only on the mass of the star, since many of the luminaries were in the same weight category.

However, it is possible that the difference in the mass of all, was simply not so significant - so astrophysicists, and failed to detect it. "We have received the first proof of the existence of special melting process inside stars. Now you need to deal with the modeling of the process of explosion of such a supernova, which forms the silver. Thus we can understand how hard was this star in a dramatic moment of his death and whether she had any special features that favour the synthesis exactly silver" - said the Professor Hansen received her results.

According to astrophysicists, this work may be of interest, on the one hand that will develop a more accurate way of estimating the mass of the supernova. On the other hand, it raises the old, but at the same time interesting question is whether only from the mass of a star depends on what the elements are obtained in the crucible of her bowels? May be, are involved in this process and other factors that scientists have not yet discovered? The answer may give only a model that offers to build Ms. Hansen.

Interestingly, unlike in deep space, on our planet gold and silver are usually still "friends". Even in native gold meet silver impurities, and in such minerals as mutant (Ag aute (Concorde)), sylvanite (AuAgTe4), petitet (Ag3AuTe2) and electrum (Ag, Au), the share of silver can reach 45-50 percent. That is, on Earth, these two elements prefer to meet together, although in space, they appear separately.

As these facts are, in turn, suggest another interesting idea. It is known that after the explosion of a supernova in the vicinity of the former star appears in all directions Roy solids, which serves as a building material for the second generation stars or stellar-planetary Solar system type. But if you are on Earth, and gold, and silver, which made different stars, it turns out that the substance from which formed the Solar system, "set" at least two lights?

Opening Hansen, if it is proved its validity, forced scientists to once again revise the view on the emergence of our stars and planets around it. Work a lot, but the results already promises to be a sensational...
