(adapted from ESO) NGC 346 is the brightest star-forming region in the neighbouring Small Magellanic Cloud 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.  It is about 4' across and easily visible in a small telescope.

Just to the right of the main nebula is the small planetary nebula LHA 115-N 70
