Conclusion
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

Aging of Cluster
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
