Resum
| Descripció |
English: In the area of NGC1929 in the LMC is found the complex nebula seen above. Known as the N44 superbubble complex, this turbulent emission nebula is dominated by a vast bubble about 325 by 250 light-years across. The bubble’s interior is formed either by massive winds produced by a cluster of a few to many OB stars combined with the remnant shell of old supernovae. If you look closely along the right of the nebula you can discern the presence of a second bubble. As superbubbles expand and age their surface brightness diminishes. Finally it is thought that superbubbles can trigger new star formation in areas of the shells where gases condense. |
