N44 is a large HII (ionized hydrogen) region in the Large Magellanic Cloud about 170,000 light years distant with the size of the "hole" about 250 light years across. It is also designated NGC1929. The large, bluish-white stars in the center of the ring or bubble create enormous stellar winds and form the giant bubble. These stars generally end up exploding as supernovae. It is likely that some of these star have in fact exploded as supernovae, helping to clean out the gases in the central part of the bubble. An X-ray source was found near the center of the bubble, supporting a supernova origin. Here are close-ups of regions of N44 designated N44F, N44C, and N44-"mouth".
