In a new study, astronomers show how gas expelled in the merger of two small galaxies can linger across vast distances for billions of years, where it may eventually feed gas to more massive galaxies to make new stars. The Large Magellanic Cloud and the Small Magellanic Cloud pictured above are a pair of dwarf galaxies that were in the process of merging when they fell into the Milky Way.
