The left panel shows a three-color composite mosaic of NGC 346 combining Webb’s F277W (blue), F335M (green) and F444W (red) filters. The region is rich in structures of knots, arcs and filaments. Areas of bright pink and/or red emission are associated with clumpy star formation. The spatially resolved PAH emission excited by ultraviolet photons in green is brightest in regions corresponding to the edges of dense material, characteristic of a photodissociation region. Massive stars, stars belonging to the BS90 cluster (circled in green) and the Small Magellanic Cloud field population are also visible. The right panel shows a mosaic image from the F335M filter showing four different populations of stars: pre-main-sequence stars (blue circles), young stellar objects with Paα (orange diamonds), young stellar objects without Paα (red squares) and stars matched with the HST-PMS catalogue (purple stars).

$This image shows WR 124, a star located approximately 15,000 light-years away in the constellation of Sagitta. The star displays the characteristic diffraction spikes of Webb’s Near-infrared Camera (NIRCam), caused by the physical structure of the telescope itself. NIRCam effectively balances the brightness of the star with the fainter gas and dust surrounding it, while Webb’s Mid-Infrared Instrument (MIRI) reveals the nebula’s structure.
