We belong to a galaxy
( cluster of stars) namely milky way
which is merry-go-round shape.
All stars are
basically fire balls which is made of gases that produce both light and
heat.This is because of the nuclear energy. The same energy which is used to
produce electricity.
The star is born from
dust and hydrogen. Which spins and
become the hot glowing prostar( beginning stage of star) . Then the prostar
starts growing nad it glows for millions of year and becomes a red gaint. Then
it begins to die.
Iron is produced due
to heat inside the star and it acts like a sponge and soaks up the star’s
energy which causes the huge explosion called as supernova.
Did you know : Our sun
is the youngest star. The next star nearest to our earth other than sun is
proxima centauri which is 1.3 billion KM away from earth.
Did you know : Still
our peoples make drawings by connecting the stars at the night. And many
astronauts follow this specific shaped star clusters for direction
identification.:
