Colleges for Astronomy/Astrophysics?

Those are great schools for physics and offer astronomy cles as well. I'd ranked the U Chicago, UIUC, then Northwestern in order of the best for physics (also consider Purdue and Notre Dame). And keep in mind you'll need a graduate degree to get a job in astrophysics - there really are not jobs in the field if you're not doing research of some kind. All of those would be good preparation for grad school, and U Chicago and UIUC would be great for grad school as well (you typically go somewhere else for grad school).
