The Sun is our main source of energy and life. The giant star is not only responsible for emitting light on our planet but is also responsible for creating and sustaining life on Earth.
Without it, life would cease to exist on our planet.
Many years ago, scientists predicted that the burning plasma ball would eventually burn up and when this happens, the Earth and all its life forms will also be destroyed.
The timeline for when the sun will die has been predicted by new research published in Nature Astronomy.
Like everything else, including massive cosmic entities, our only star, the Sun also has a lifespan.
Scientists have long been fascinated by the birth and death of the huge fiery star responsible for life on our planet.
The Sun, estimated to be around 4.6 billion years old, first materialized from a molecular cloud composed of helium and hydrogen.
Previously, experts predicted that the Sun would become a planetary nebula, a bright bubble of cosmic gas and dust. This research by the University of Manchester said that the star will shrink and become a white dwarf. However, further research on the subject revealed that the Sun would need to be larger to become a planetary nebula.

A more recent study published in the journal Nature Astronomy reveals that the Sun will die in the next 10 billion years or so. This new research contradicts the study published in 2018, which reveals that the Sun will become a red giant, not a white dwarf, in the next 5 billion years.
The Sun’s core will contract when it runs out of fuel.
According to NASA, after becoming a red giant, the Sun’s outer layers will expand so much that it will reach the orbit of Mars, simultaneously melting and devouring the planets closest to it, including Earth, if the planet still exists by then. . All of these events will take approximately 10 billion years to occur.
However, humans will not be around to see the death of our only star. It is estimated that all life forms on planet Earth will cease to exist in approximately one billion years.

The Sun’s brightness increases approximately 10% every billion years. The Sun produces about 4.26 million metric tons of energy per second and even a 10% increase would have disastrous consequences for the planet. As?
Greater brightness means more heat reaches our planet. More heat will mean that water masses present on Earth, including our oceans, will evaporate and the surface will become too warm for fresh water to develop. And so, without water, the planet and all its life forms will perish.
However, theories are circulating that while humans and most other living things will die in the next billion years, other life forms will develop that can withstand the scorching heat.

Whatever the case, one thing is certain: humans only have a billion years to survive, unless we can find another habitable planet to live on.
