At a distance of only 200,000 light years, the Small Magellanic Cloud is one of the Milky Way's closest galactic neighbours. Thanks to its brutal treatment by our galaxy's gravity, the galaxy has massive regions of active star formation, and regular supernova explosions. ...

Fraser. The same process works for the Local Bubble that we live in. The outer perimeter of the Local Bubble is thought to have formed from the passage of several giant stars from the OB Centaurus-Sco association. It was Steve Strom of UMass who first suggested that companion stars from the same primordial cloud would have near identical spin axes, though it is unlikely that they"died together" as the article suggests. Simultaneous multiple supernovae in a single galaxy are rarities indeed . Successive supernovae separated in time are far more likely. Pete.

Is every orangish blob a supernova pushing out? What makes the green arcs close to a few of the blobs?
