Here’s a good visual as to how a star goes through it’s various different phases in life.
How A Star Works-Link
I already knew that our sun generates it’s heat by fusing hydrogen into helium, but that’s about all I knew of it’s inner workings. This sheds a lot of light on why larger stars burn out faster and why some stars go out super nova style and some go out gracefully. After watching this I guess you could say a star is a chain of fusion reaction and it’s mass dictates how far it will be able to go in terms of building heavier materials.
Kudos to whoever made this!
