Jakarta, CNN Indonesia —
Currently experts say age Sun 4.6 billion years and is expected to die in about 10 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.
In about 5 billion years, the Sun will turn into a red giant. The star’s core will shrink, but its outer layers will expand into the orbit of Mars and engulf Earth in the process.
“We know that solar winds in the past eroded the Martian atmosphere, which, unlike Earth, lacks a large-scale magnetosphere,” study co-author Aline Vidotto, an astrophysicist at Trinity College Dublin, Ireland, said in a statement. Live Science.
“What we didn’t expect was that future solar winds could damage even planets protected by magnetic fields.”
What happens if 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 gas and light 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 huge red giant and die. The sun will slowly die into a white dwarf.
Quoted from 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.
In addition to 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.
