NGC 3324 is anopen cluster in the southern constellation ofCarina, located northwest of theCarina Nebula(NGC 3372)[3][4] at a distance of 9,100 ly (2,800 pc) from Earth.[2] It is closely associated with theemission nebulaIC 2599, also known asGum 31.[5] The two are often confused as a single object, and together have been nicknamed the "Gabriela Mistral Nebula" due to its resemblance to theChilean poet.[6][7][8]NGC 3324 was first catalogued byJames Dunlop in 1826.[3]

TheHubble Space Telescope observed a western section of NGC 3324 in detail, and the same section was among the first observations of theJames Webb Space Telescope for comparison.

Nearby clusters

[edit]

NGC 3324 is associated with the open clusterNGC 3293. Both are fairly young, at around 12 million years old. They show some degree ofmass segregation, with more massive stars concentrated near their centers. Neither aredynamically relaxed.[2]
