Galactic dynamics
The Galactic Fountain
Star formation and supernovae blow hot gas out of the disc, which cools, condenses, and rains back down as clouds — a continual circulation between the disc and the halo. This galactic fountain recycles and mixes gas, and helps deliver the fresh material that keeps the Milky Way forming stars.
