Jakarta, Spasi-id.com - The Sun is a source of light and the center of the solar system. Living things can't survive without sunlight. So basically the sun is needed.
But is it sometimes when the sun doesn't shine or die? According to various astronomical models and math calculations and astrophysics, the Sun will "die" someday. However, when will that "someday" be? Are we ready?
Here's an estimate of whether or not the Sun dies or is no longer shining:
- The sun died a long time ago.
The death of the Sun is long, few trillion years away. So, can we still breathe freely? Wait a minute!
We have to consider the sun's main series, the phase in which the hydrogen nuclear fusion in the Sun allows the star to emit energy and to put enough pressure on it to keep the Sun going. Most likely, this main series cycle will end in 5.—10 billion years.
"Our sun is almost 5 billion years old, or it's middle-aged. Most likely, the Sun will die about 10 billion years," said Paolo Testa, an astrophysicist expert at the Center for Astrophysics, at Live Science.
- The sun will be big
After the Sun burns most of the hydrogen in its core, this star will turn to the stage "Red Giant." According to NASA, most likely, this phase will occur in the next 5 billion years. The sun will stop producing heat through nuclear fusion and its core becomes unstable and contracting.
Meanwhile, NASA continues that the outside of the Sun that still contains hydrogen will expand and blush as it enters the cooling. In this phase, the Sun will "swallow" the first two planets, Mercury and Venus, and blow the solar wind that destroys the Earth's magnetic field and destroys its atmosphere.
- End of Earth
Since the magnetic fields and atmosphere of the Earth are no longer working, it is certain that the Earth's creatures have also perished the end of the Sun. According to the US research forecast in 2014 that was contained in the Geophical Research Letters journal, the Sun can vaporize the entire Earth Ocean in one.—1.5 billion years.
Earlier, a joint research between the British and the Mexicans which was contained in the Monthly Notice of the Royal Astronomical Society in 2008 was also warning the end of the Earth.
- Death of the Sun
Then, the Sun began to melt helium from hydrogen fusion to carbon and oxygen. After that, it's just the Sun is consumed by its own core.
The good news is that the nebula in the outer layer of the sun as the star shrinks and heats up the size of the Earth. Paolo estimates the nebula will be visible for 10,000 years.
Once the "White Katai," the Sun and all the rest will spend trillions of years cooling off and becoming dead sky objects.
