Scientists know that stars form from the collapse of huge hydrogen clouds that are squeezed under gravity to the point where nuclear fusion ignites. But only about 30 percent of the cloud’s initial mass winds up as a newborn star. Where does the rest of the hydrogen go during such a terribly inefficient process?

Astronomers had assumed that a forming star blows off gas through stellar winds and jets.

They should also create cavities in the surrounding gas that widen until the cloud dissipates.
