When will our sun die? .. Scientists reveal an epic explosion of our star that will destroy the Earth


Astronomers agree that our sun inevitably perishable, and will eventually die, but how and when this will happen has been the subject of constant scientific debate, and one study suggests that humans will die long before death of the sun.

When does our sun die?

According to the study, which was published in Nature Astronomy earlier this year, the sun will “die” in about 10 billion years, and stars, like the sun, start to “die” when they burn all their hydrogen fuel.

According to RT, at this point, it expands and becomes a very large type of star called a red giant.

It is believed that this stage will happen to our sun within five billion years, and it is expected that the sun will expand so much that it will swallow Mars and the Earth during its transformation into a red giant, as the core of the star will shrink, but its outer layers will extend to the orbit of Mars, which will swallow it with our planet in the process .

Scientific predictions indicate that humans will die before that time unless we find a way to leave the planet and live elsewhere.

A study by an international team of astronomers, published in 2018, says that the sun is expected to become 10 percent brighter every billion years, and this could create some major problems for life on Earth.

This increase in brightness would end life on Earth, as our oceans would evaporate, the surface would be too hot for water to form, and for a while Earth would look like Venus, trapped in a stifling atmosphere of carbon dioxide, and then it gets worse.

And if the expansion of the Sun reaches our world, the Earth will melt in less than a day.

But even if the expansion of the Sun were to stop for a short time, it would not be good for Earth, and the intense energies emitted by the Sun would be intense enough to vaporize rocks, leaving only the dense iron core of our planet behind.

The study indicates that when the sun completes the red giant phase, it will become a white dwarf, and then end up as a planetary nebula. This means that our star will turn into a glowing shell of hot gas, and this type of nebula is very common throughout the visible universe, and can be observed by its brightness from distances that may reach millions of light years.
