Astronomers figured out what happens after the death of the Sun
MOSCOW, may 7 — RIA Novosti. After the death of the Sun, our star system will turn into a giant glowing “bubble” of dust and gas that will last in this state for several thousand years, and then disappear, say scientists in an article published in the journal Nature Astronomy.
“Observations showed that the stars as the Sun can produce bright nebulae, the theory said it was impossible — it requires twice as a big star. We were able to show that it is possible for stars of a solar mass that settled the dispute long in 25 years,” said albert Zijlstra (Albert Zijlstra) from the University of Manchester (UK).
Approximately after 4.5−5 billion years our Sun will exhaust the reserves of hydrogen, “nuclear fuel” and will begin to burn helium, causing his bowels are heated to ultrahigh temperatures, and the outer shell, the light will swell up, engulfing Venus and mercury and plunging the Earth into a lifeless glowing ball.
Eventually, the Sun will get rid of all the outer layers of gas and become a white dwarf — a small but very hot star, which continues to glow due to the residual heat remaining in the former core. His light will warm up and illuminate the surrounding clouds of gas, turning them into a bright spot in the night sky other worlds, and the Solar system will become a so-called planetary nebula.
In this destiny light, as noted by Zijlstra, today no one doubts, however, scientists for almost three decades arguing about how it will look in its planetary nebula and whether it will exist at all.
