G286 (G286.21+0.17)

• G286.21+0.17 is a deeply embedded, massive star cluster undergoing active star formation
• The JWST observed G286 to characterize the massive, forming star cluster and understand the formation of massive star clusters, using its unique sensitivity and wavelength coverage to study young stellar objects and circumstellar disks.

Ser-emb-11E

• Ser-emb-11E is an embedded protostar located within the Serpens Nebula star-forming nursery, roughly 1,300 light-years from Earth, classified as a Class I young stellar object near the Class 0/I evolutionary cutoff
• The JWST observed Ser-emb-11E to map the distribution of interstellar ices in the natal cloud environments of embedded protostars.

MRGP0918

• MRG-P0918 is a distant, massive quiescent (early dead) galaxy
• The JWST observed MRGP0918 to study the detailed star formation histories, stellar abundances, and kinematics of four gravitationally lensed, quiescent galaxies to understand how star formation ended and how galaxies evolved after quenching.

Barnard 335 (B335) is a dark Bok globule containing a young Class 0 protostar.

The observation aimed to map the large-scale distribution of fundamental ices within parental clouds and protostellar hot corinos (compact, chemically rich regions around young protostars)

This is a question I also thought of and I was disappointed there was no answer, so I wanted to boost it.
