N44 H II Region Wall Art including Frame t-shirt Astronomers aren't sure how ringsThis 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
