Arabia Weather - The sun will not live forever. In the very distant future, it will turn into a giant red ball and then shrink to become a white star, and then life on Earth will disappear. There is nothing we can do but move and live somewhere else.
The Sun is much larger than any planet, most of its composition is hydrogen, and very high temperatures cause hydrogen atoms to transform into helium atoms. This process (known as thermonuclear fusion) produces a lot of energy, and it is this energy that produces all the heat and light of the sun.
Heat and light from the Sun's core travel very slowly through the Sun's layers toward the surface. Even while some heat and energy are lost in the process, the temperature on the Sun's surface is approximately 5,500 °C (10,000 °F).
When the Sun exhausts its supply of nuclear fuel, about 5 billion years from now, it will evolve into a giant, swollen red ball, engulfing Venus and Mercury and burning Earth. After shedding its outer layers in the form of a colorful planetary nebula, the Sun will then shrink into a small white dwarf star. The white dwarf stars are still hot, but not as hot as the Sun is now.
Eventually, our star will fade and become a “black star,” where very little of its original form remains. Black dwarf stars are not hot and do not produce any energy.
But long before that, the Sun's temperature will gradually rise. Less than a billion years from now, Earth's water will begin to boil. It is unlikely that humans will be alive at that time, so it is better to worry about other short-term problems that threaten the Earth's habitability.
Over the next few billion years, the Sun's temperature will gradually rise. About 5 billion years from now, it will turn into a giant red ball, leading to the extinction of all life in the inner solar system. - Image source: supernova
So life on Earth would not be possible without the light and heat of the sun, so the news of the death of the sun is bad, but fortunately for us, this will not happen until a few billion years from now and we probably will not be around then.
The James Webb Telescope captured a new image of what is known as a “ring nebula,” a huge gathering of dust and gas resulting from the explosion of a star at the end of its life. This image gives us an overview of the fate of the Sun, which is the star around which the Earth and the rest of the planets in the solar system revolve.
The ring nebula captured by the James Webb Telescope, also known as Messier 57, is located about 2,600 light-years from Earth. The name "Messier 57" indicates that this nebula was one of the targets included in Messier's famous catalog of non-stellar celestial objects.
This nebula was created as a result of the explosion of an ancient star. When this explosion occurs, the star's outer layers are thrown away, and this process gives the nebula its vibrant appearance with wonderful colors and details.
The new image taken by the James Webb Telescope shows previously unknown details in the outer parts of the nebula, such as arcs and structures that formed after the life of the star that ultimately led to this explosion. These arcs formed when the star was a giant before it shed most of its components and became the dwarf star it is now.
