Understanding the Sun

The video explores the Sun's vital role in supporting life on Earth, its composition as a star made of burning gas, and its gravitational influence on the solar system. It covers the Sun's size, temperature, and the speed of its light reaching Earth. The Sun's atmosphere, consisting of the photosphere, chromosphere, and corona, is explained, along with the mystery of the corona's high temperature. The Sun's age, its future as a red giant, and eventual collapse into a white dwarf are discussed. The video concludes with a fun fact about the Sun's 'degrees.'
