3. Outline Star Formation Star Evolution Observations
Comparison of Isochrones
Aging of Cluster
Conclusion

4. Star Formation Gas clouds come together by gravity
Then it heats up and gives off light in order to cool down
Then it shrinks and the core heats up until fusion starts,which begins the main sequence

5. Star Evolution

8. Observations

9. Comparison of Isochrones

10. Aging of Cluster

11. Conclusions
M 13 is about 13.6 billion years old +/- 1.5 billion years, which means that the universe is about 13.6 billion years old or older
This is one of the best methods that scientist have used to be able to measure the age of the universe
