How long will our Sun continue to shine if it has been around for four and a half billion years? Like the Sun, stars are estimated to burn for nine to ten billion years on average. So, our Sun has completed almost half of its lifetime. But do not fret. There are still approximately 10,000,000,000 ten billion years left.
The Sun will turn into a huge red orbital object after those five billion years are up. That implies that the Sun will increase in size while also cooling down. The Sun as we know it today won’t exist when that occurs. Our Sun will shine 2,000 times brighter than it does now as a red behemoth!
However, here we have more interesting info that is based on a new Nature Astronomy research.
When the sun goes out: scientists calculated the date and modeled the “death” of the sun
Scientists have predicted when the Sun will go out and what the last days of the solar system will look like.
What will be the “death” of the Sun
Based on observations of other stars, astronomers suggest that he still has 10 billion years to live.
According to computer simulations used in the studies, our Sun will probably undergo a red giant to white dwarf transition before becoming a planetary nebula, just like 90% of other stars.
In about 5 billion years, the Sun will begin to “reincarnate” into a red giant. Its core will shrink, but the outer layers will expand to the orbit of Mars and swallow our planet.
Scientists contend that humanity won’t still be around by then. Given that the brightness of the Sun grows by 10% every billion years, the Earth won’t be habitable after 1 billion years.
Due to the increase in the brightness of the Sun, the oceans will evaporate, and the surface of our planet will become too hot for water to form.
“When a star dies, it ejects a lot of gas and dust into space. The hot core makes them glow brightly for another 10,000 years. This is what makes planetary nebulae visible. They are so bright that they can be seen from extremely long distances,” he explained. one of the authors of the article, astrophysicist Albert Zijlstra.
The Helix Nebula, the Cat’s Eye Nebula, the Ring Nebula, and the Bubble Nebula are some of the most well-known planetary nebulae in the universe.
