Study - Universe
Our best links about studying the universe. Covering Hertzsprung-Russell diagrams, Parallax, and nuclear processes that go on in the sun.
The Hertzprung-Russell diagram is a tool that shows relationships and differences between stars. It is something of a "family portrait."
A brief description of the Hertzsprung Russell diagram and different star types
Read how stars like our sun use the proton-proton chain to generate energy by turning hydrogen to helium
How do we turn hydrogen into helium and make energy? A simple explanation of the nuclear fusion process that goes on in our sun.
What nuclear fusion reactions go on inside stars, and what does it depend on? Find about the proton proton chain reaction.
The fusion reactions of the CNO Cycle allows bigger stars to convert hydrogen to helium.
Definition of parallax, a method used to measure the distance to stars.
