NGC 346, the brightest star-forming region in the neighbouring Small Magellanic Cloud (SMC) galaxy, some 210,000 light-years away from Earth. The light, wind and heat given off by massive stars have dispersed the glowing gas within and around this star cluster, forming a surrounding wispy nebular structure that looks like a cobweb. NGC 346 is located in the constellation Tucana and spans approximately 200 light-years.
