Space Science: Sun As A Star (1970)

The film discusses the Sun, our nearest star, detailing how astronomers study it through solar observatories. It explains the Sun’s characteristics, including its size, temperature, and composition, and compares it to other stars using the Hertzsprung-Russell diagram. The Sun is identified as a yellow star of spectral type G, and its lifecycle is outlined, from its formation from a gas cloud to its eventual transformation into a red giant and white dwarf. The film also touches on nuclear fusion processes occurring in the Sun’s core, which generate energy and sustain its life.
