LHA 120-N 44 (or N44 for short) is an emission nebula (H II region) of some 1,000 light-years across, located about 157,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way, toward the southern constellation of Dorado.
This very rich region of gas, dust and young stars surrounds NGC 1929, a rich large cluster of bright young, blue-white stars, and is without doubt the original source of the material that formed these stars that produce intense radiation.
LHA 120-N 44 is dominated by a cosmic superbubble. This superbubble, of roughly 325 by 250 light-years across, is expanding outwards due to an interaction between two destructive forces generated by the stars at its center: Young stars in the cluster send out streams of charged particles (or stellar winds) that have cleared out the bubble center, and massive stars have exploded to create supernovae shock waves that push the gas out further.
LHA 120-N 44 has a smaller bubble structure inside known as N44F which has been shaped in a similar manner; it has a hot, massive central star with an unusually powerful stellar wind that moves at 7 million kilometers per hour. This is because it loses material at 100 million times the rate of the Sun, or approximately 1,000,000,000,000,000 tons per year. Synthetic beautiful photos from space, solar system, galaxies, galaxy
