Star cluster NGC 1929 is a star forming region embedded in the N44 nebula inside the Large Magellanic Cloud. Many of the stars that form are extremely massive and produce intense radiation. Given that massive stars have very short lifespans, the region has many cavities (called superbubbles) that have been formed by winds and shock waves from supernova explosions.
