Basic Information about the sun         Since the birth of mankind,

Basic Information about the sunbathe         Since the birth of mankind, the Earth has been literature by the vibrant miniature of our closest star, The Sun. The sun, which is roughly 1 au from the earth, is a giant ball of burning gases, without some(prenominal) solid. The Sun was born approximately 5 billion eld ago, as it began its formation in a bulky cloud of gases. As the materials condensed, high temperatures and great pressures built up at the center. These conditions set off a nuclear response that still releases zipper and causes this star to continuously shine. This nuclear reaction, know as nuclear fusion, produces 386 billion megawatts of energy per second. This solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion ms Earths air pressure at sea level) is so intense that these nuclear reactions take place. This reaction causes quatern protons or total heat nuclei to fuse together to form unrivalled alpha atom or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The disparity in mass is expelled as energy and is carried to the surface of the Sun, done a process known as convection, where it is released as light and heat.

Energy generated in the Suns core takes a million eld to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter.

The atmosphere         The atmosphere of the sun is also referred to as the corona of the sun. The corona begins about 2,500 km above the surface and stretches out beyond the orbit of the earth. The...
