Paragraph 2
The Sun is still
young in space years. It is just 4.6 billion years old. This means it is only around one
into its lifespan. Professor Albert Zijlstra, a
from the University of Manchester, explained what happens at the
of a star's life. He said: "When a star dies, it ejects a
of gas and dust into space....This reveals the star's core. By this point in the star's
, it is running out of fuel." He said it eventually turns off and dies. Professor Zijlstra was
that modern science can calculate the age of
and what will happen to them. He said we can measure the
of stars in distant galaxies, and "we
have found out what the Sun will do when it dies".
