Our mission is to advance the  knowledge of the Universe through research in astronomy and astrophysics and in related areas of fundamental physics and geophysics. This mission includes service to the national and international astronomical communities, and to society in general, in areas associated with our primary research imperative.

I’d like to welcome you to our Center, and hope that as you explore the wide range of activities and inquiries made here, you feel yourself imbued with the same wonder and curiosity that set each of us on our own journey in astrophysics.
