Detail of N44 in the Large Magellanic Cloud
This image of the spectacular N44 H II region in the LMC displays (very nearly) its central region, which is dominated by a large, ring-shaped nebula that includes a bright stellar association of very luminous stars. It emits X-rays - this is interpreted as a sign that several heavy stars in this area have exploded as supernova during the last few million years. N44 is a very bright, rich and well-studied complex in the LMC, somewhat apart from the other nebulae in this galaxy. The general appearance (in astronomical terminology: the "morphology") is well explained by a combination of fast outflow from stars (stellar winds) and supernova remnants, as well as sequential star formation.
