NGC 346 in the Small Magellanic Cloud

NGC 346 (N 66, DEM S 103) is a bright compact star cluster, wrapped in nebulosity, located in the Small Magellanic Cloud. It was first seen by James Dunlop during his stay at Paramatta, Australia.

It is the largest and most luminous HII region in the SMC and has a cluster of young massive stars in its heart. It is a site of ongoing star formation and is a smaller version of the more famous Tarantula Nebula (NGC 2070) in the nearby Large Magellanic Cloud. Compared to the Orion Nebula, NGC 346 emits about 60 times more energy in H-alpha, so it is no light-weight in the bigger picture!

Reference: Heydari-Malayeri, M. & Selier, R. (2010) "A very young component in the pre-eminent starburst region of the Small Magellanic Cloud". A&A 517, A39.
