Why does the Samoan flag have the Southern Cross on it?

There are five white, five-pointed stars on the blue representing the constellation the Southern Cross, which is a prominent constellation of the southern hemisphere.

The five stars symbolize the constellation the Southern Cross, representing the stars Alpha, Beta, Gamma, Delta and Epsilon, which is smaller because it doesn't shine as brightly as the other stars in the constellation. The cross represents Samoa's geographical position in the world and its link to New Zealand, which also incorporates the Southern Cross on its national flag.
