This star provides all the energy necessary to
sustain life on Earth.
 Our Sun is not unique in the universe. It is a
common middle-sized yellow star which
scientists have named Sol.
 There are trillions of other stars in the
Universe just like it. Many of these stars have
their own systems of planets, moons,
asteroids, and comets.
 The Sun was born in a vast cloud of gas and
dust around 5 billion years ago. The nebulae
are the birth places of all stars.
At the center, an ever growing body of mass
was forming. As matter falls inward, it
generates a tremendous amount of heat and
pressure. As it grew, the baby Sun became
hotter and hotter. Eventually when it reached
a temperature of around 1 million degrees, its
core ignited, causing it to begin nuclear
fusion.
Nuclear fusion is
how stars produce
their light,
heat, and energy.
Through this
process, they
“burn” a fuel
known as
hydrogen. The
result is that they
create another
type of matter
known as helium.
 Heat rises, while cooler gas falls. Because heat rises,
while cooler gases fall, the gas within stars is
constantly rising and falling. This creates massive
streams of circular motion within the star. This is
called convection.
 As the gases near the core of the Sun are heated, they
begin to rise towards the surface. As they do so, they
cool somewhat. Eventually, they become cool enough
that they begin to sink back down towards the core. It
can take an atom millions of years to complete one
complete cycle around a convection stream.
These are areas which are slightly cooler.
However, sun spots are still very hot. It appears
slightly dark in color because the area is cooler
compared to its surrounding areas.
Sun spots come and go on a regular
basis.
At times there are very few if any sun
spots. Other times there are far more.
They generally increase in intensity and
then decrease over a period of 11 years.
This 11 year cycle is known as the
Saros Cycle.
 During periods of high solar activity, the Sun
commonly releases massive amounts of gas and
plasma into its atmosphere.
 On occasion these more powerful flares can
even cause satellites on orbiting the Earth to
malfunction.
 They can also interact with the Earth's magnetic
field to create impressive and beautiful light
shows known as the Northern and Southern
lights.
 As the Sun burns hydrogen at its core, it releases
vast amounts of atomic particles, or pieces of
atoms into outer space. These atomic particles,
along with the Sun's radiation create a sort of
wind, known as the solar wind.
 This wind blows particles outward in all
directions from the Sun.
 The surface of the Sun is much cooler than its
atmosphere.
 The Sun's surface is a warm 6,000 degrees
Celsius.
 This is the same temperature as the Earth's
core.
 The sun can stay in this balanced state for a total
of about 10 billion years.
 Given the sun's age as about 4.6 billion years,
one can assume we have 5 billion years or so to
go.
 Eventually most of the hydrogen in the center
will get used up, and the sun will enter a dying
phase.
