With the detection of gravitational waves, the ongoing robotic exploration of the solar system, and a powerful new generation of ground- and space-based observatories under construction, the astronomical sciences are now poised to embark on a bold new voyage of discovery. 

Help us build a foundation for this exciting future by making a legacy investment to the AAS Initiative Endowment Fund.

Outright Gifts

The AAS is happy to work with you on making gifts of publicly traded securities that have appreciated in value. These gifts often provide a greater tax benefit than an equivalent gift in cash.

Deferred Gifts

Name the American Astronomical Society as a primary or contingent beneficiary of your retirement or other financial account.
