Nothing new one day The sun will “die”, Only now, according to a documented study, scientists’ predictions indicate that the impacts on Earth will come much earlier, as they are already saying when and how it will be. This information may be shocking and curious, so we have separated the main topics for this study. Keep reading and learn more about the topic.
Understand what will happen to the sun
Based on ESA research, the average age of the Sun is 4.57 billion years, and the end of its life should be about 10 billion years. However, a star-mapping mission carried out by the agency’s Gaia spacecraft found other information.
At the moment, the Sun undergoes a stable process of nuclear fusion, in which hydrogen and helium nuclei fuse. However, the hydrogen will gradually run out, heating and contracting the core and causing the Sun’s outer atmosphere to expand. In this expansion process, Earth and other planets will be destroyed. This process is expected to occur within 5 billion years, or even sooner, and will turn the star into a red giant.
What are the consequences of gradual expansion?
When the temperature cools, what we know as the Sun will become a white dwarf. But when the two gases in the star’s core run out, the process will reach its final stage and a planetary nebula will be formed. This data was also analyzed in a computer model and the astronomers confirmed that this process is the same as for most stars.
However, despite estimates for the end of the planet 5 billion years from now, the brightness of the Sun is expected to increase by 10% every billion years. This “small” difference will lead to a significant increase in surface temperatures, so there will be no condensation of the water, which will lead to evaporation from our oceans.
