NGC 346 in the Small Magellanic Cloud

How and why are all these stars forming? Found among the Small Magellanic Cloud's (SMC's) clusters and nebulae NGC 346 is a star forming region about 200 light-years across, pictured above by the Hubble Space Telescope. A satellite galaxy of the Milky Way, the Small Magellanic Cloud ( SMC ) is a wonder of the southern sky, a mere 210,000 light-years distant in the constellation of the Toucan ( Tucana ). Exploring NGC 346 , astronomers have identified a population of embryonic stars strung along the dark, intersecting dust lanes visible here on the right. Still collapsing within their natal clouds , the stellar infants' light is reddened by the intervening dust. A small , irregular galaxy, the SMC itself represents a type of galaxy more common in the early Universe . But these small galaxies are thought to be a building blocks for the larger galaxies present today. Within the SMC , stellar nurseries like NGC 346 are also thought to be similar to those found in the early Universe .
