Why is the Hertzsprung-Russell Diagram, like the one below, significant to astronomers?
- Astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
- Astronomers can use the diagram to tell how big a star is compared to the light it emits, and predict where new black holes will be formed.
- Astronomers can see the red shift in any star in the diagram, and use that information to tell how far away the star is.
- Astonomers can know from the chart if a star is similar in structure to our sun, and use it as a predictor for how likely that star will have another world like earth that we can inhabit.
