U.S. National Committee for IAU

The National Academy of Sciences is the U.S. adhering body of the International Astronomical Union (IAU) and it maintains its relationship with the union through the U.S. National Committee (USNC)/IAU. The IAU’s mission is to promote and safeguard the science of astronomy in all its aspects through international cooperation.

Preparations Underway for IAU General Assembly, 2018
The IAU General Assembly (GA) takes place every three years.  Spread evenly over two weeks, the next GA will be held August 20-31, 2018 in Vienna, Austria.  The GA offers an opportunity for astronomers worldwide to meet together to discuss current and emerging topics in all fields of astronomy.  See for more information.

IAU Individual Membership Application Period Now Open Until February 2, 2018
 The International Astronomical Union (IAU) is the oldest of the international scientific unions, and one of the few that includes individual as well as national members.  Applications for individual IAU membership are first considered by the adhering body of each National Member who recommends to the IAU those individual who meet the requirements for Individual Membership.   The U.S. National Committee for the IAU (USNC-IAU) acting for the National Academy of Sciences, Engineering, and Medicine, which is the adhering body for the United Sates, will accept applications for IAU membership until February 2, 2018.  Applicants applying via the USNC-IAU should be at least three years past a PhD in astronomy or related field or have related experience, be planning on a career related to astronomy, be a U.S. citizen or living and working in the United States, or if not a U.S. citizen hold a green card, HI-B or J visa.  Holders of other visa types or those working in the U.S. on a time limited postdoctoral position should normally apply for IAU membership through their home country.
This year for the first time, the IAU will consider applications for a new category of Junior Member.  Applicants applying for Junior Membership through the USNC-IAU are expected to have received a PhD in astronomy or a related field, be planning on a career related to astronomy, be a U.S. citizen, or be living and working in the United States.
Application forms for both Regular and Junior IAU Membership can be found through the following links:
Applicants will be notified before the end of March if they are being recommended for IAU Membership, and will be notified by the President of the IAU if they have been accepted after the IAU General Assembly in August, 2018. Providing a CV in the application is helpful, though not required.
IAU membership is not required to participate in the General Assembly or IAU Symposia, but is encouraged for professionals working in astronomy or related fields who may want to take a more active role in the affairs of the Union.  Members and non-members may apply for travel grants to participate in the General Assembly and/or related symposia through the IAU web site.  Information on AAS travel grants can be found at and are due January 5, 2018.  There are no individual dues related to Regular or Junior IAU Membership, but IAU Members are expected to take an active role in the Union through its Divisions, Commissions, or Working Groups.
