• ===>> We know that the sun is very important to us but the main question is why. We all understand that the sun supplies Earth with never ending energy that we use in multiple ways. The energy comes in as heat and light and we transform the energy in different ways to create electricity. But how is the energy created and how it gets to Earth? The formation of sun’s energy lies within its core and radiates outward and travels out to Earth and the rest of the solar system. Our sun is the central part of our solar system; if the sun didn’t exist several things wouldn’t occur: the process of photosynthesis would not take place, oxygen cannot be created, therefore, life cannot be present. The sun and its sunlight give us access to many resources. Sunlight helps the plants produce oxygen and overtime create fossil fuels. The importance of the sun is both positive and negative, the more we study and understand the sun we learn to advance our society. The suns positive effects help us find and progress ways to gain renewable resources, such as creating wind power, dams and solar energy. The negative effects of the sun include climate changes and damaging of the ozone, and harmful effects on humans that result in sunburn, eye damage, and damaging of the skin: skin cancer and premature aging. The sun produces two different Ultraviolet Radiations (UV rays), UVA and UVB. The sun effects earth in many ways to carry on life and that’s why it is very important. It gives us the privilege to energy: heat and light, oxygen, water, electricity, and many more. It’s truly amazing how this star of gas can create many things to save our life’s and it is important that we understand the reasons why, and not always take it for granted. Who knows scientist say that after another 5 billion years there may not be a sun anymore.

➡️➡️➡️As we look up in the night sky we see stars from end to end. Our Sun is no more than a star, It is our proximity to the Sun which makes it so bright and large in size. The Sun was born about 5000 million years ago as a result of the contraction of clouds of hydrogen, helium and dust into a ball under gravitational pressure. Very soon nuclear reactions began to take place in this ball and the Sun became as we see it today.

The Sun is located in the Milky way galaxy and has a family of nine planets. The distance between Earth and the Sun is about 150 million kilometres, the Sun also rotates on its axis, taking 25.4 days to do so. It has a surface temperature of 5,5000 centigrade and a core temperature of 1,50,00,0000 centigrade. Life on the Earth is sustained by the Sun which provides both light and heat.

The Sun is in reality a glowing ball of gases comprising of mainly three parts of hydrogen and one part of helium besides other elements. In the dense core of the Sun hydrogen atoms are crushed together to form helium; this reaction releases large amounts of intense light and heat. The energy released by this reaction travels to the surface of the Sun in the form of electromagnetic waves including light waves, radio waves and heat waves. Glowing hydrogen gas is frequently released with great force into the sky, upto heights of 55,000 kilometres or more in the form of what we know as ‘Prominences’.

Changes in the Sun’s magnetic field cause large black spots to appear on it’s surface, these are known as Sun spots and are relatively cool areas. Around the Sun there exists a thin white atmosphere of gases called the Corona. Considering the current rate at which reactions are taking place in the Sun, it is expected to last for another 5,000 million years before it runs out of fuel and begins to die.
