NGC 346 is one of the most active "stellar nurseries" in our neighborhood: a cluster of young stars illuminates and expels surrounding gas, forming distinctive filaments, arcs, and cavities.
This nebula, which contains an open cluster and is self-luminous due to the ionization of its own gas, is located in the Small Magellanic Cloud, a dwarf satellite galaxy of the Milky Way, approximately 200,000 light-years from Earth.
The image clearly shows the "debris" left behind by a burst of star formation: dust and gas that are heated, fragmented, and thrown aside by shock waves, giving way to new stars.
The image was obtained by NASA's James Webb Space Telescope in the mid-infrared range; the image was released on October 10, 2023. Infrared observations enable us to see many stars that are inaccessible to optical instruments due to extremely dense clouds of dust blocking their light.
