The Birth of Suns

A video presentation by Mark Krumholz, U.C. Santa Cruz professor of Astrophysics and  researcher on star formation

We normally think of space as empty, but it's not. The space between the stars in our Galaxy contains, on average, about 1 atom per cubic centimeter. That's a better vacuum than the best vacuum chamber we know how to make, but there are a lot of cubic centimeters in interstellar space, and the mass between the stars of our Galaxy adds up to about 10% of the mass of all the stars. It is from this interstellar medium that new stars are continually born, at a rate of about 1 new Sun per year. In this talk Professor Krumholz describes our current understanding of the gas in interstellar space, and how and why it condenses to make new stars.
