By: Dee Friesen


Presented February 23, 2019. Follow the life cycle of our own star, the sun. The various phases of this particular star, Sol, is examined, using the Hertzsprung-Russell (H-R) Diagram, as it moves through its life cycle. Also discussed is the origin of the elements. Hydrogen and helium resulted from the original Big Bang, but the birth, life, and death of a star are described in terms of nuclear reactions, and the chemical elements that make up the matter we observe throughout the universe were created in these reactions.

Highlights the contribution of the female “Harvard Computers”, such as Annie Jump Cannon, who worked with Edward Charles Pickering on a system for classifying stars based on their temperatures, which eventually became the official classification system.
