Spectroscopic observations of cluster candidates in galaxy NGC 1023 reveal that faint fuzzy clusters are younger and belong to the disk, unlike older globular clusters. These findings provide new insights into the origins and evolution of different star cluster types.

Why it matters: Understanding faint fuzzy clusters helps explain star cluster formation and survival in galaxy disks.

The big picture: Faint fuzzies are younger, metal-rich, and disk-bound, while globular clusters are older and more spatially dispersed.

Stunning stat: Faint fuzzy clusters have ages between 7-9 billion years, compared to globular clusters older than 10 billion years.

The stakes: Distinguishing cluster types clarifies galaxy evolution and the dynamics of star cluster survival in different environments.
