✨🔭🧪 Looking ahead to #HWO25, inspiration from 1989: the 1st JWST workshop proceedings, 9 months b4 Hubble’s launch. On cover: the then-imagined groundbreaking observations of a galaxy at redshift ONE. How far we’ve come! #HWO25 will shape a similar 'community science book' for the next era.

the cluster catalog is useful testing stellar population models, and for studies astrophysics. As (effectively) single-age populations, they have great utility as “clocks” for timing various phases of the star formation cycle. The catalog is available at archive.stsci.edu/hlsp/phangs

this is what the UBVI color-color diagram looks like with ~15,000 clusters from many nearby galaxies. Blue, young populations are at the top left. The BC03 track of a solar metallicity single-age population (SSP) is overlaid. As clusters age, they become redder and end up in the bottom right.
