It's hard to believe, but the stars shine at night the same way Sun shines during the day.


The sun is also the star closest to the Earth. We know that all our life depends on the sun. Without the heat of the sun, life would not exist on Earth. Without sunlight, there would be no green plants, animals, humans.

The sun is located at a distance of more than 172 million km from the Earth. The mass of the Sun is 1,300,000 times the mass of the Earth. But, interestingly, the Sun is not as solid as the Earth.

It is very simple to prove: the temperature of the sun's surface reaches 6,000 ° C. Any metal or stone turns into gas at this temperature, so the sun must be a ball of gas!

In the past, scientists believed that sunlight and heat are the results of combustion. But the surface of the Sun has remained hot for hundreds of millions of years, nothing can continue to burn for so long.

Scientists today believe that the sun generates heat as a result of processes similar to nuclear fusion in the atomic bomb. The sun converts mass into energy.

This process is completely different from burning. While burning, one form of material transforms into another. In the conversion of mass into energy, a minimum amount of element is required to produce a huge amount of energy.

So, if science is right, the sun shines because there is a constant transformation of mass into energy. One percent of the Sun's mass is enough to keep it active for 150 billion years!
