100th Anniversary of the IAU

This year, the International Astronomical Union (IAU) is celebrating its 100th anniversary. Let's make sure that together, we’ve set the right tone for the next 100 years!

In July 1919, one month after the Treaty of Versailles was signed, a Constitutive Assembly was held in Brussels with the goal of creating the International Research Council (IRC), and under its authority, a number of international scientific unions. Among these, the IAU was the first to be founded — therefore the official birth date of the IAU is 28 July, the day that the Statutes of the IRC were adopted.

The IAU is an internationally recognized astronomical association that brings together more than 13 500 professional astronomers from more than 100 countries worldwide. The IAU also maintains friendly relations with organizations that include amateur astronomers in their membership. Its mission is to support and improve the science of astronomy in all its aspects through international cooperation as a tool for education, development and diplomacy.

The IAU 100th anniversary provides a great opportunity to tell the whole world about wonderful science, technology and inspiration that astronomy has brought us over the past century.
