The Sun’s Fate: Transforming into a Planetary Nebula

Astronomers believe that the Sun will turn into a planetary nebula.

Scientists have predicted what the end will look like Sunand with it, probably, our entire planetary system.

About it writes Science Alert.

An international group of scientists has concluded that transformation into a planetary nebula is the most likely scenario for the end of the Sun’s life.

Scientists estimate that humanity will exist for about a billion years if it does not find a way to leave the Earth. This will happen because the Sun’s brightness increases by about 10% every billion years. This increase in brightness will end life on Earth. The oceans will evaporate and the planet’s surface will become too hot to support liquid water.

But what will happen after the Sun turns into a red giant is difficult to predict. Several preliminary studies have shown that for a planetary nebula to form, the original star must be twice as massive as the Sun.

“When a star dies, it releases a mass of gas and dust into space known as its envelope. The envelope can be half the star’s mass. This opens up the star’s core, which by this point in the star’s life has run out of fuel, eventually shutting down before finally dying. The hot core causes the ejected shell to shine brightly for 10 thousand years – the short period in astronomy that makes a planetary nebula visible, some of them so bright that they can be seen from extremely large distances, measured in tens of millions of light years, although the star itself was would be too hazy to see,” said astrophysicist Albert Zijlstra of the University of Manchester in the UK.

Let us recall that a study by scientists previously showed that the Sun expects many changes that will occur much earlier, foreshadowing the end of the solar system.

And a NASA spacecraft called SOHO, using its instruments, recorded a deadly dive comets in the Sun.
