In the Large Magellanic Cloud
(LMC), there is a lovely ring shaped
nebula, Henize 70 (also known as
N70 and DEM301). It is actually a
luminous "superbubble" of
interstellar gas about 300 lightyears
in diameter, blown by winds from
hot, massive stars and supernova
explosions, its interior filled with
tenuous hot expanding gas. These
superbubbles offer astronomers a
chance to explore this crucial
connection between the lifecycles
of stars and the evolution of
galaxies.
