"The Sun: Our Life-Giving Star in the Cosmos"
Introduction The Sun, a magnificent celestial body at the center of our solar system, is the source of life, light, and energy for our planet. With its fiery core, the Sun's significance extends far beyond its role as the ultimate source of daylight. In this article, we will explore the Sun's composition, its life cycle, the energy it radiates, and its impact on Earth and the entire solar system. With 4.6 billion years of existence and an estimated 5 billion more to go, the Sun continues to be a captivating subject of scientific study and human fascination. Composition and Structure The Sun primarily consists of hydrogen (about 74%) and helium (approximately 24%). These elements undergo nuclear fusion in the Sun's core, where temperatures exceed 15 million degrees Celsius. This process results in the release of vast amounts of energy in the form of light and heat. Surrounding the core is the radiative zone, which extends to about 70% of the Sun's radius, and the conve...
