In what year or years will the sun finally expire?

About 4.6 billion years old, our sun controls our weather, seasons, climate, and ocean currents and makes life possible on Earth by facilitating photosynthesis in plants.

Scientists have been fascinated about the creation, life, and death of the massive star responsible for controlling Earth for a long time. Scientists are increasingly curious as to how and when the sun, like other stars, will erupt and die, what with all the talk about global warming and other disasters.

In a story from approximately 4.5 billion years ago, National Geographic states that the sun began to develop from a molecular cloud consisting of helium and hydrogen. Many researchers believe that the sun was born when a powerful shockwave from a nearby supernova impacted a cloud of dust and energized it.

According to a research by ScienceAlert, our star, which is approximately 150,000,000 km from Earth, may die in 5 billion years. The Sun will soon become a red giant, according to scientists.

“Although the star’s core will contract, its outer layers will grow to encompass Earth and Mars. In the unlikely event that it still exists.”

Researchers at the University of Manchester concluded in 2018 that the sun, like 90% of stars, is likely to become a white dwarf and then a planetary nebula.

At its death, a star ejects its envelope, which is a “mass of gas and dust,” according to Albert Zijlstra, an astrophysicist from the University of Manchester and one of the paper’s authors.

He suggested that the envelope could contain as much as half of the star’s mass.

This exposes the star’s nuclear furnace, which at this late stage in its existence is about to shut down and die.

He continued by explaining that the nebula’s long lifespan—nearly 10,000 years—is due to the star’s heated core. This is what allows us to see the planetary nebula.

According to Zijlstra, this envelope is so incredibly luminous that it can be seen from tens of millions of light-years distant.
