The sun is a star at the center of our solar system that produces an immense amount of energy. It holds 98.8% of the total mass of the solar system and has a diameter 109 times that of Earth. The sun was born approximately 4.6 billion years ago from the collapse of a large cloud of dust and gases under the force of gravity, forming a hot, dense center that became the sun surrounded by planets. Sunspots, which are darker and cooler than surrounding areas, are caused by powerful magnetic fields emerging from below the sun's surface. Sometimes large eruptions from sunspots called solar storms can reach Earth and disrupt communication systems. Without the sun providing energy, life on Earth would not be possible as plants

2. WHAT IS SUN ACTUALLY ?
We live in a unique system called solar system. It
includes the sun , eight planets and other celestial
bodies. The sun is the main member of this solar
family. Now the question arises that-what is sun
actually? So the answer is that sun is a star at the
center of our solar system. The diameter of sun is 109
times of earth that is 1.39 million kilometers . Its
mass is about 330,000 times that of the earth the
surface temperature of sun is about 5800 K and the
temperature of its core is about 15,600,000 K. It
holds about 98.8% of total mass of whole solar
system. It is not a matter of joke that about one
million earths could fit inside the sun. One would
need to explode 100 million tons of dynamite to match
the energy which is produced by our huge sun.

3. HOW SUNWAS BORN ?
It is the story of the birth of the sun, the story
starts before 4.6 billions of years ago According to
the scientist a large cloud of dust and gases called
nebula in the space was disturbed , due to explosion
of star supernova or some other reason. Due to the
explosion waves were made in the space and these
waves squeezed the cloud of dust and gases.
Squeezing made the cloud start to collapse, as the
Gravity pulled the gas and cloud together forming
The solar nebula. It span like a dancer spins his or
her arms and finally the cloud was collapsed. Now,
it became hotter and denser at the center, which was
surrounded by many gases and dust. It was hotter
at the center but cooler at the edges. So this hot and
dense center took the role of sun and the edges
became planets.

4. WHAT ARE SUN SPOTS ?
Sunspots are magnetic in nature. They are the places
where the Sun's magnetic field rises up from below
the Sun's surface and those magnetic regions poke
through .they are the active. They are darker than
the surrounding areas because they expend less energy
and have a lower temperature. They are caused by
the Sun's magnetic field welling up to the
photosphere, Which is the Sun's visible surface. The
powerful magnetic fields around sunspots produce
active regions on the Sun, which often lead to solar
flares and Coronal Mass Ejections Our Sun isn't
the only star with spots. These spots of the sun can
be visible through a normal telescope with a solar
filter. They can also be seen in the above pictures in
this slide.

5. SOLAR STORMS !
Now we have understood the meaning of the sun spots and
the formation of the sunspots. So it is not much difficult
to under stand the meaning of solar storms. We know
that the sun spots are the active region so, due to the
magnetic fields these spots eject the coronal mass from
sun’s core. These ejections some times are very massive so
that the can reach earth also which are called the solar
flares or storms. Planet mercury in every ejection remains
the victim of the solar storms. These storms if more
massive then can create a lot of destruction in our planet.
Due to these solar storms the surface temperature of the
earth increase that much that it is not possible to move
out of our houses. Some times these storms cause
destruction to the magnetic field also. It is said that
planet mars was having life on it but due to solar storm
the magnetic field got disappeared and the life ended.

6. IS LIFE POSSIBLE WITHOUT SUN ?
The sun has a great use not only in the magnetic field
or vitamin D but more than this, let us take an
example that if sun is not there for a month. We all
know that human beings and the plants are dependent
on each other at night time the plants inhale the oxy
gen and exhales the carbon dioxide, if there will be no
sun then it will be night only. Then we the human
beings can’t inhale carbon dioxide for a month so we
will die. After sometime the water on the earth will
star freezing then the plants will also die. Due to this
the marine animals will die. Some species of polar
animals will sustain for sometime but not for very
long time.
So the sun is alive so we are alive but on
the other hand it is a destroyer also.
