It also turns out that stars eject mass throughout their lives (a kind of wind blows from their surface layers) and that material must go somewhere. Our Galaxy contains vast quantities of this “raw material”—atoms or molecules of gas and tiny solid particles between the stars. Studying this diffuse matter between the stars helps us understand how new stars form and gives us important clues about our own origin.
