Speaker: Jason Tumlinson (STScI)

It is is common to think of galaxies as vast collections of billions of stars. Such a view is only partly correct, for it overlooks the great clouds of gas and dust in galaxies; the clouds from which those stars were born. How galaxies of all types acquire that gas is a major unanswered question in modern astrophysics. The study of this question has been developing for over six decades. However, late-breaking results from Hubble's new Cosmic Origins Spectrograph has provided some fresh insight.

The 2010 Public Lecture Series offers talks on a diverse selection of cosmic topics held the first Tuesday of every month in the STScI John N. Bahcall Auditorium. Admission is free and free parking is available in the lot across the street. Find information related to driving directions and relevant transportation resources on our Getting Here page.
