Though the Spiderweb protocluster is well-studied, because of Webb’s capability to see infrared light, scientists are using it to observe regions of the Spiderweb that were previously hidden to us by cosmic dust.

The characteristics of the new galaxies Webb has spotted are shedding light on how galaxies grow and interact as clusters form. Most galaxies in local clusters are old and not very active. The ones in the Spiderweb are comparatively adolescents.

Surprises? The previously-known galaxies in the Spiderweb galaxy cluster are not as dusty as we thought. This may be because their star formation and growth are not being triggered so much by galaxy mergers, but by gas accumulating around the cluster

Is this a “surprise” because most other clusters fuel growth by mergers first and then by any gas accumulation? Love the details here!
