How will our sun be looked after? The final days of our Solar System will be predicted by scientists. We will not be able to see the Sun's curtain call.
The Sun was thought to be a planetary nebula until evidence suggested it was a tad more massive.
The most likely solar corpse is a planetary nebula, according to an international team of astronomer.
The age of other objects in the Solar System is gauged by the age of the Sun. It will reach the end of its life in about 10 billion years.
Things will happen along the way. The Sun is going to become a red giant in about 5 billion years. Our planet will be engulfed by the outer layers of the star when it shrinks, but the core will remain. It is still there.
We will not be around by that time. If we don't find a way off this rock, we'll only have 1 billion years left. The Sun is getting brighter every billion years.
The increase in brightness will end life on Earth. The surface will become too hot to hold water. We'll be pretty much the same as you can get.
The red giant has been hard to pin down. In order for a bright planetary nebula to form, the initial star has to be twice the size of the Sun.
Our Sun is most likely to shrink down from a red giant to a white dwarf and then end as a planetary nebula, according to the study.
A mass of gas and dust is ejected from a star when it dies Half the star's mass can be found in the envelope. Albert Zijlstra from the University of Manchester in the UK is one of the authors of the paper.
There is a brief period in astronomy when the ejected envelope shines brightly. The planetary nebula can be seen. Some are so bright that they can be seen from tens of millions of light years away.
The life cycle of different kinds of stars is predicted by the data model created by the team.
There are a number of famous planetary nebulae, including the Cat's Eye Nebula and the Ring Nebula.
There is a cat's eye Nebula.
The first ones were discovered by William Herschel in the late 18th century and they were similar to planets through the telescopes of the time.
Astronomers noticed that the planets in other galaxies all have the same level of brightness. Calculating how far away the planetary nebulae are can be done by looking at the planets in other galaxies.
The data showed that this was correct, but the models disagreed, which has been vexing scientists since the discovery.
Old, low mass stars should be more faint than young, more massive stars. The conflict has been going on for 25 years.
The models said that it was not possible to get bright planetary nebulae from low mass stars like the Sun.
The problem has been solved by the models that show that the Sun is less mass than a star that can produce a visible nebula.
A star with a mass less than 1.1 times the Sun's will not produce a visible nebula. The brighter the nebulae, the bigger the star.
The predicted brightness is very close to what has been seen.
Zijlstra said that the result was a nice one. We now have a way to measure the presence of stars of a few billion years in distant galaxies, which is a range that is remarkably difficult to measure, and we have found out what the Sun will do when it dies.
The research was published in an astronomy journal.
