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


Astronomers agree that our sun is inevitably mortal, and will eventually die, but how and when this will happen has been the subject of constant scientific debate.

One study suggests that humans will die long before the sun does.

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, begin to “die” when they burn up all their hydrogen fuel.

At this point, it expands and becomes a very large type of star called a red giant.

It is believed that this phase will occur to our sun within five billion years. The sun is expected to expand so much that it will swallow Mars and Earth as it turns into a red giant, as the star’s core will shrink, but its outer layers will extend into the orbit of Mars, which will swallow it up 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, and the surface would become too hot for water to form. For a while, Earth will 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 stopped for a short time, it would not be good for the Earth. The intense energies from the sun will 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. This type of nebula is very common throughout the observable universe, and can be observed by its brightness from distances that may reach millions of light years.
