SSN 7 is a so-called contact binary located in the Small Magellanic Cloud, a dwarf galaxy some 210,000 light-years away in the constellation of Tucana. Also known as MPG 435, this binary system is a member of the very young stellar cluster NGC 346.

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).
