The nearby Large Magellanic Cloud (LMC) is a very active star-forming galaxy. The most massive region of star formation is around 30 Doradus (the Tarantula nebula) which can be seen with the unaided eye, but hundreds of lesser examples are visible with a telescope. This picture shows one of the more intriguing, NGC 2014 (Henize 55). It contains cluster of hot, young stars, almost hidden in the brightest part of the nebula. The energetic ultraviolet light from these stars is absorbed by hydrogen and produces the distinctive red glow from an enormous distance around the cluster.
As well as radiating strongly in ultraviolet light (a result of their high temperature) massive young stars also produce vigorous stellar winds. Eventually they will disperse the hydrogen around them, evacuating a bubble-like nebula. To the left of the main cluster a single star has begun this process, creating a strange hollow shape.
This picture was made photographically from three glass plates taken with the UK Schmidt telescope. These plates cover the whole LMC and many images of individual objects can be made from them. In contrast, modern CCD detectors image only a small part of the sky, but when used on a big telescope like the AAT they show much more detail. An AAT CCD picture of NGC 2014 is here.
