Catalog names

N44 is an emission nebula in a satellite galaxy of the Milky Way, the large Magellanic Cloud , in the constellation Swordfish . The emission nebula was cataloged by Karl Henize in 1956 with an extension of 1,000 light years and a distance of 160,000–170,000 light years. N44 has a superbubble structure formed by the radiation pressure of a centrally located cluster of 40 stars; the stars are blue-white and very bright. A smaller bladder, labeled N44F, has similarly formed; it has a hot and massive central star with a strong stellar wind that has a speed of 7 million kilometers per hour and transports about 100 million times more material than that of the sun. In other areas of N44 dust columns have arisen in which stars are formed . The different densities were probably caused by past supernovae in the vicinity of N44. This is also corroborated by the X-rays that N44 emits.

The first observers noticed the nebula structure and noted the position of particularly bright areas, which were then recorded in the New General Catalog or in the Index Catalog .
