Will the Sun one day become a black hole?

Once everything comes to an end. Our Sun in this regard is no exception: after about 5 billion years after you reading this article, our star suddenly swell to the size of a red giant with a fully Ismailov nearby planets, including our own. But what happens next? Turned into a red giant in an ordinary black hole or planetary nebula, finally adorned the Solar system with colored gas?

In about 5 billion years could begin the process of dying of our stars

As the portal nasa.govthe likelihood that our Sun will one day be able to turn into all-consuming black hole — miserable. The fact that the size of our star is too small for that, so before the death of our Sun simply “inward curved back on itself” under its own gravitational forces.

To the Sun was able to come to this impressive scenario, our star needs to be about 20 times more massive. Star, having such size, were at risk of becoming a supernova at the end of the major period of his life, having formed after his death the black hole — real cosmic monster, whose gravitational pull is so strong that nothing, not even light, can escape its tenacious grip.

Some stars are large enough to become supernovae, but their mass is too small to become black holes: they are the quanta collapse into the dark in a very dense structure, called neutron stars, formed just after the supernova explosion. Our Sun, unfortunately or fortunately, is not high enough for such a fate: it has only approximately one tenth of the mass, which is usually necessary in order to one day turn an ordinary neutron star.

So what will happen to the Sun? Scientists believe that in about 5 billion years it would turn into a white dwarf, which is a small and very dense ball, glowing from residual heat.

Such a transformation in the Universe is not something unusual: like most of the stars of the vast cosmos, the Sun constantly generates a large amount of energy by burning hydrogen atoms in its core. The death of our star will be caused by the complete depletion of its natural fuel, which will cause our light to melt their heavier elements in the core. When this happens, the temperature of the Sun will begin to rise, and the outer layers of its atmosphere will expand so far into space that they engulf the Earth with all its inhabitants, turning such worlds as Titan or Pluto, potentially habitable places. The red giant phase will last about a billion years, after which the Sun will become in the previously mentioned white dwarf, surrounded by colorful planetary nebula.
