JWST colour-composite (F410M/F182M/F115W for RGB) image of the Spiderweb protocluster. The 22 ALMA sources detected by JWST and the eight undetected ones are marked with orange and white squares, respectively, with their IDs labelled nearby. The Spiderweb galaxy is marked as a star, which represents the centre of the protocluster. The dashed circle shows the r₅₀₀ = 229 kpc derived from the recently detected Sunyaev–Zeldovich signal (Di Mascolo et al. 2023).
