The Trifid Nebula itself represents the final phase of star formation.

三叶星云本身代表着恒星形成的最后阶段。

On the other hand, because of the wide range of open clusters in ages, from dozens of Myr to 10 Gyr, it can help us investigate the stellar properties of different ages and constrain the star formation theory.

另一方面，疏散星团的年龄跨度很大，从几十Myr到10个Gyr。这有助于研究不同年龄的恒星性质，对恒星形成理论能有较好的约束。
