A supernova is the death or the beginning of a new life?

Quite rare people can observe such an interesting phenomenon as a supernova. But this is not the ordinary birth of a star, because in our galaxy, up to ten stars are born each year. A supernova is a phenomenon that can be observed only once in a hundred years. So bright and beautiful die the stars.

To understand why a supernova explosion occurs, we must return to the very birth of the star. In space, hydrogen flies, which gradually gathers into clouds. When the cloud is large enough, condensed hydrogen begins to collect in its center, and the temperature gradually rises. Under the influence of gravity, the nucleus of the future star gathers, where due to the increased temperature and increasing gravitation, the reaction of thermonuclear fusion begins to pass. On how much hydrogen can attract a star, depends on its future size - from the red dwarf to the blue giant. Over time, the balance of the star's work is established, the outer layers press on the core, and the nucleus expands due to the energy of thermonuclear fusion.

The star is a kind of thermonuclear reactor, and like any reactor, one day it will run out of fuel - hydrogen. But to see how the supernova exploded, a little more time must elapse, because in the reactor, instead of hydrogen, another fuel (helium) was formed, which will start burning the star, turning it into oxygen, and then into carbon. And this will continue until the iron core is formed in the core of the star, which, when a thermonuclear reaction, does not emit energy, but consumes it. Under such conditions, a supernova explosion may occur.

The core becomes heavier and colder, resulting in lighter upper layers begin to fall on it. Again, the reaction of thermonuclear fusion is launched, but this time is faster than usual, as a result of which the star simply explodes, scattering its matter into the surrounding space. Depending on the magnitude of the star, after it may also remain small "stars." The most famous of them are black holes (a substance with an incredibly high density, which has a very large force of attraction and can emit light). Such formations remain after very large stars, who were able to produce thermonuclear fusion to very heavy elements. Smaller stars leave behind themselves neutron or iron small stars, which almost do not emit light, but also have a high density of matter.

New and supernovae are closely related, because the death of one of them can mean the birth of a new one. This process continues indefinitely. A supernova travels millions of tons of matter into the surrounding space, which again gathers into clouds, and the formation of a new celestial body begins. Scientists claim that all the heavy elements that are in our solar system, the Sun at the time of its birth, "stole" from the exploded star. Nature is amazing, and the death of one thing always means the birth of something new. In open space, matter disintegrates, and in the stars it forms, creating a great balance of the universe.
