The Harvard-Smithsonian Center for Astrophysics (CfA) combines the
resources and research facilities of the Harvard College Observatory (HCO)
and the Smithsonian Astrophysical Observatory (SAO) under a single director.
The CfA is a thriving research collaboration between
two great observatories, but it is not a separately incorporated legal
entity. Therefore, tax-deductible contributions in support of the CfA
should be made to either the Harvard College Observatory or to the
Smithsonian Astrophysical Observatory. Please click below to donate to
Smithsonian Astrophysical Observatory.
Thank you!
