We report on extremely high velocity molecular gas , up to -80 km s ^ { -1 } relative to the ambient medium , in the giant star-formation complex 30 Doradus in the Large Magellanic Cloud ( LMC ) , as observed in new 22 GHz H _ { 2 } O 6 _ { 16 } \rightarrow 5 _ { 23 } maser emission spectra obtained with the Mopra radio telescope .
The masers may trace the velocities of protostars , and the observed morphology and kinematics indicate that current star formation occurs near the interfaces of colliding stellar-wind blown bubbles .
The large space velocities of the protostars and associated gas could result in efficient mixing of the LMC .
A similar mechanism in the Milky Way could seed the galactic halo with relatively young stars and gas .
