A portion of the dwarf galaxy Wolf–Lundmark–Melotte (WLM) captured by the James Webb Space Telescope’s Near-Infrared Camera. The image demonstrates Webb’s remarkable ability to resolve faint stars outside the Milky Way. Color translation: 0.9-micron light is shown in blue, 1.5-micron in cyan, 2.5-micron in yellow, and 4.3-micron in red (filters F090W, F150W, F250M, and F430M).
