New Individual Membership

Individual memberships are available to those actively involved in advancing astronomy or a related branch of science. Former members who have left the field are also welcome to rejoin as Alumni Affiliates. Application for admission to the AAS no longer requires nomination by two Full Members of the American Astronomical Society. [Note: Corporations and other entities desirous of encouraging the work of the Society should join as a Corporate Member.]

To join the Society:

  1. Read the eligibility requirements and choose the appropriate Membership Class.
  2. Complete the appropriate AAS Membership Form.
  3. Nomination by an AAS Full Member is an eligibility option when joining as a Full Member or International Affiliate. Applicants seeking nomination must enter the name and email address of their endorser in the appropriate fields in the online membership form. Doing so will trigger an email to be sent to your nominator, who will then reply back to the AAS directly with their endorsement.
  4. Submit the completed form with payment to the AAS Executive Office.

Once we receive your application and process your payment (typically a 48-hour process during business hours), your contact information is entered into our in-house database.
