“The Sun will die”, is what the European Agency says; see what will happen

It's not news that one day the sun will "die", but now, according to a documented study, the predictions of scientists are that the impacts on Earth will come much sooner and they also say when and how this will happen. This information can be shocking and curious, so we separate the main topics of this study. Keep reading and learn more about the topic.

Understand what will happen to the Sun

Based on research by the European Space Agency, the average age of the sun is 4.57 billion years and the end of its life should be around 10 billion years. However, the stellar mapping mission carried out by the agency's Gaia spacecraft found other information.

At the moment, the sun is in a stable process of nuclear fusion, in which its core of hydrogen and helium are fusing together. Gradually, however, the hydrogen will 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 devastated. This process is expected to occur within 5 billion years, or even sooner, and will transform the star into a red giant.

What are the consequences of the gradual expansion?

As the temperature cools, what we know as the Sun will become a white dwarf. But, when the two gases present in the star's core run out, the process will reach its final stage and a planetary nebula will be formed. Such data also underwent an analysis in a computational model and astronomers confirmed that this process is the same as that which occurs with most stars.

However, despite estimates for the end of the planet to be 5 billion years from now, it is expected that every billion years the Sun's brightness increases by 10%. This “small” difference will cause a significant increase in surface temperatures and, consequently, there will be no water condensation, which will lead to evaporation from our oceans.
