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  
stars combined with the
remnant shell of old
supernovae. If you look closely
along the left 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.
