Jakarta, CNN Indonesia —
Earth need sun exposure Sun to revive every kind of living being. Every second, minute and hour of light particles emitted by the Sun means a lot to life on Earth.
A burst of heat called the solar wind hits Earth at a speed of about 1.6 million kilometers per hour. These hot particles penetrate the atmosphere and reach the Earth’s surface.
But some experts predict the Sun will one day die. Currently experts call the age of the Sun 4.6 billion years.
In a study published in the journal Monthly Notices of the Royal Astronomical Society, a team of astronomers calculated how the Sun’s intensity would evolve over the next 5 billion years and run out of hydrogen energy. Experts say that currently the Sun is still in a stable cycle.
“We know that solar winds in the past eroded the atmosphere of Mars, which, unlike Earth, does not have a large-scale magnetosphere,” study co-author Aline Vidotto, an astrophysicist at Trinity College Dublin, Ireland, said in a statement.
“What we didn’t expect was that future solar winds could damage even planets protected by magnetic fields.”
What happens when the Sun dies?
The sun will eventually run out of hydrogen. Astronomers predict that when hydrogen runs out, the Sun will become a nebula or an explosion of light gas and dust that fills space. Nebulae are the remains of stars that have died.
Without hydrogen, the Sun’s core would begin to “contract”, while the force of gravity began to take over the Sun’s core. Eventually, the star will just become a dead big red giant. The sun will slowly die into a white dwarf.
Quoted Space, to avoid that the Sun needs to grow twice from now. If that happens the Sun manages to survive its cataclysmic transformation, and planet Earth will be saved for the next 5 billion years.
Quoted Live Science, Besides being a reminder of life on Earth about the apocalypse, this research has implications for the search for extraterrestrial life.
Some astronomers think the extinction of the Sun will actually lead to new life on planets around the Sun such as Mercury, Venus, Mars and Earth though.
This indicates it is highly unlikely that life on the planet could survive the death of the Sun.
