International Astronomical Union

The International Astronomical Union, or IAU, is a special group that helps scientists who study the stars, planets, and everything in space. It started on 28 July 1919 in Brussels, Belgium, and today its main office is in Paris, France.

The IAU has many members from different countries. These members are scientists who study astronomy. They work together in groups to learn more about space.

One of the most important jobs of the IAU is to give official names to stars, planets, and other objects in space. This helps everyone use the same names and rules when they talk about space. The IAU also works with other groups, like UNESCO, to share their knowledge with the world.

Every three years, the IAU holds a big meeting called the General Assembly. Scientists from all over come together to share their discoveries and make important decisions. These meetings help everyone stay updated on the latest space news and research.

The IAU wants to make sure that people everywhere can learn about and enjoy the wonders of the universe. It works with schools and science groups to teach children and adults about astronomy in fun and exciting ways.
