Our sun, which is around 4.6 billion years old, controls the weather, seasons, climate, and ocean currents. It also enables photosynthesis in plants, which supports life on our planet.
Scientists have long been interested in the birth, death, and genesis of the enormous star that controls our planet. Scientists are growing increasingly curious about how and when the sun, like other stars, will erupt and die in light of the present debate on climate change and planetary disasters.
According to a National Geographic research, the sun began to develop from a helium and hydrogen molecular cloud almost 4.5 billion years ago. According to scientists, a supernova near to the sun released a shockwave that was so powerful that it struck this cloud and charged it, resulting in the creation of the sun.
According to a report by ScienceAlert, the sun, which is located 150 million kilometres from Earth, could perish in five billion years. The specialists predict that the Sun will eventually become a red giant.
“The star’s outer layers will eventually envelop our planet as the star’s core contracts and moves toward Mars’ orbit. If it’s still there at all.”
According to a 2018 study from the University of Manchester, the sun will eventually become a planetary nebula after contracting to the size of a white dwarf, like 90% of other stars.
Astrophysicist Albert Zijlstra from the University of Manchester, one of the paper’s authors, noted that when a star dies, it expels its envelope, which is a “mass of gas and dust.”
According to him, the envelope may contain up to half the star’s mass.
This displays the star’s core, which at this stage in its life is exhausting its fuel and will eventually turn off before dying.
He continued by saying that the nebula’s ability to glow brightly for almost 10,000 years, which is a brief period in astronomy, is due to the star’s heated core. The planetary nebula is visible because to this.
Due to its extraordinary brightness, this envelope can be observed from tens of millions of light years distant, according to Zijlstra.
