Our Sun will die in 10
billion years from now (17th November, 2022)
Scientists have worked out when our Sun will die. It
won't be any time soon. It will be in 10 billion years. The scientists are from
the University of Manchester in the UK. They predict that in about 5 billion
years from now, the Sun will turn into a "red giant". This is the
scientific name given to a star at the end of its life. When our Sun becomes a
red giant, its centre will shrink. Its outer layers will expand as far as Mars.
This means Earth will be burnt and disappear. After our Sun turns into a red giant,
it will become a planetary nebula. This is a bubble of gas and space dust. The
scientists say no humans will be on Earth when the Sun dies out. Humans will disappear in around one billion years from
now.
The Sun is still
quite young in space years. It is just 4.6 billion years old. This means it is
only around one third into its lifespan. Professor Albert Zijlstra, a scientist
from the University of Manchester, explained what happens at the end of a
star's life. He said: "When a star dies, it ejects a mass of gas and dust
into space.…This reveals the star's core. By this point in the star's life, it
is running out of fuel." He said it eventually turns off and dies.
Professor Zijlstra was happy that modern science can calculate the age of stars
and what will happen to them. He said we can measure the presence of stars in
distant galaxies, and "we even have found out what the Sun will do when it
dies".
