The James Webb Space Telescope Early Release Science (ERS) program—first released on July 12th, 2022—has proven to be a treasure trove of scientific finds and breakthroughs. Among the many areas of research it is enabling, there’s the study of resolved stellar populations (RSTs), which was the subject of ERS 1334. This refers to large groups of stars close enough that individual stars can be discerned but far enough apart that telescopes can capture many of them at once. A good example is the Wolf-Lundmark-Melotte (WLM) dwarf galaxy that neighbors the Milky Way.
