The James #Webb Space Telescope would probably not be your first choice for observing the large open #StarCluster of the #Pleiades but the authors of the paper "JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium" - arxiv.org/abs/2602.03672 - did it anyway, to study the turbulent energy cascade in the CNM the cluster happens to move through right now. Here is what they saw, with the NIRCam and the F335M filter - for the four cuts from the JWST pictures at the bottom in detail see fig. 2 of the paper.
