The outer arm of the spiral in this huge, oddly shaped stellar nursery -called NGC 346- may be feeding star formation in a river-like motion of gas and stars. This is an efficient way to fuel star birth, researchers say. The Small Magellanic Cloud has a simpler chemical composition than the Milky Way, making it simil...
