What will Happen to the Sun When it Dies?
  • Sun will shift into a planetary nebula when it dies

The Facts are Here Regarding the Scenario of the End of Our Star, the Sun

Scientists are agreed upon one thing. This is that the sun will last five billion years more before collapsing. They were unsure of what the aftermath of this star death will be, but not anymore.

A group of researchers made the prediction that it will convert into a large halo of bright interstellar gas and dust. This is what we normally call a nebula. Over 90% of all stars end up as nebulas. The stars turn from red giants into white dwarves.

Scientists used to think that the sun was somehow different from other stars. The mass of the sun was thought to be too little for it to follow the normal routine star death scenario.

The group of researchers made a model of the evolution of stars. This showed the brightness of these stars too. One of the researchers said that “when a star dies, it ejects a mass of gas and dust”. This is known as an “envelope”. “The envelope can be as much as half the star’s mass”.

The star seems to lose its fuel and thus end up depleted. According to the researcher, “the ejected envelope shines brightly for around 10,000 years – a brief period in astronomy”.

Another problem has been solved thanks to this research effort. There was a mismatch between the models and the data. This thought has been resolved and it is a definite article of scientific fact now that the sun will form a nebula when it finally dies.

The research is published in the journal Nature Astronomy.
