Astronomical Union (IAU) was founded in 1919. Its mission is to promote and safeguard the science of astronomy in all its aspects, including research, communication, education and development, through international cooperation. Its individual Members — structured into <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/divisions/">Divisions</a>, <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/commissions/">Commissions</a>, and <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/working_groups/">Working Groups</a> — are professional astronomers from all over the world, at the Ph.D. level and beyond, who are active in professional research, education and outreach in astronomy. The IAU also has Junior Members. The IAU has a total membership of 12461. The <a href="/web/20221002093724/https://iau.org/administration/membership/member/">Individual and Junior Members</a> Directory contains 12161 names in 93 countries worldwide. These Members are labeled as "active" in the IAU database meaning they have a valid email (are able to vote and stay connected to the IAU activities) and are affiliated to at least one Division. IAU membership spans 93 countries. Out of those countries, 85 are <a href="/web/20221002093724/https://iau.org/administration/membership/national/">National Members</a>. In addition, the IAU collaborates with various scientific organizations all over the world.</p> <p>The long-term policy of the IAU is defined by the General Assembly and implemented by the <a href="/web/20221002093724/https://iau.org/administration/executive_bodies/executive_committee/">Executive Committee</a>, while day-to-day operations are directed by the <a href="/web/20221002093724/https://iau.org/administration/executive_bodies/executive_committee/#officers">IAU Officers</a>. The focal point of its activities is the <a href="/web/20221002093724/https://iau.org/administration/secretariat/">IAU Secretariat</a>, hosted by the Institut d'Astrophysique de Paris in France. The scientific and educational activities of the IAU are organized by its 9 Scientific Divisions and, through them, its 38 specialized Commissions covering the full spectrum of astronomy, along with its 46 Working Groups.</p> <p>The key activity of the IAU is the organization of scientific meetings. Every year the IAU sponsors 9 international IAU Symposia. The <em>IAU Symposium Proceedings</em> series is the flagship of the IAU publications. Every three years the IAU holds a General Assembly, which offers 6 IAU Symposia, some 15 Focus Meetings, and individual business and scientific meetings of Divisions, Commissions, and Working Groups and Offices. The proceedings of Focus Meetings are published in the <em>Astronomy in Focus</em> series. The triennial reports of the Divisions and Commissions are published in the <em>Transactions of the IAU</em> - A series.The reports of the GA business meetings are published in the <em>Transactions of the IAU</em> - B series.</p> <p>Among the other tasks of the IAU are the definition of fundamental astronomical and physical constants; unambiguous astronomical nomenclature and informal discussions on the possibilities for future international large-scale facilities. Furthermore, the IAU serves as the internationally recognized authority for assigning designations to celestial bodies and surface features on them.</p> <p>The IAU also works to promote research, education and public outreach activities in astronomy for the public. These activities culminated with the organization of the UNESCO International Year of Astronomy in 2009, which reached out to over 800 million people from 148 countries. Following this effort, the IAU has also established in 2015 the <a href="/web/20221002093724/https://iau.org/education/office_for_young_astronomers/">Office of Young Astronomers (OYA) </a> , a joint venture with the Norwegian Academy of Sciences and Letters. In 2011 the IAU created the <a href="https://web.archive.org/web/20221002093724/http://www.astro4dev.org/">Office of Astronomy for Development</a> (OAD), a joint venture with the South African National Research Foundation where Astronomy is used as a tool for stimulating capacity building. The IAU has also established in 2012 the <a href="https://web.archive.org/web/20221002093724/https://www.iau.org/public/">Office for Astronomy Outreach</a> (OAO), a joint venture with the National Astronomical Observatory of Japan. Furthermore, the IAU has also established the <a href="https://web.archive.org/web/20221002093724/https://www.iau.org/education/office_for_young_astronomers/">Office of Young Astronomers</a> (OYA), a joint venture with the Norwegian Academy of Sciences and Letters. The IAU has recently launched an international call to establish the <a href="https://web.archive.org/web/20221002093724/https://www.iau.org/education/oae/">Office of Astronomy for Education</a> (OAE) in 2019. Regional nodes have been created in <a href="https://web.archive.org/web/20221002093724/http://www.astro4dev.org/regional-offices-activities/">other countries</a> as well. In 2015 actively participated in the <a href="https://web.archive.org/web/20221002093724/https://www.iau.org/static/public/iyl//InternationalYearOfLight.zip">International Year of Light</a>. The IAU also carries out joint educational activities associated with COSPAR and UNESCO.</p> <p><a href="https://web.archive.org/web/20221002093724/https://www.iau.org/public/images/detail/iauoffices-diagram/"><img src="https://web.archive.org/web/20221002093724im_/https://www.iau.org/static/archives/images/screen/iauoffices-diagram.jpg" width="100%"></a></p> <p>This web site provides on-line information on the Union's activities and links to the web sites of the IAU <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/divisions/">Divisions</a>, <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/commissions/">Commissions</a> and <a href="/web/20221002093724/https://iau.org/science/scientific_bodies/working_groups/">Working Groups</a>.
