IAU XXXII General Assembly Concludes

The meeting makes history as first General Assembly held in Africa and first to be fully open access

The IAU will change its digital interface in 2025. It is expected to become visible to the public and our members from March 2025.

This is a significant effort driven by a small team, and we appreciate your understanding during the transition.

We thank ESO for its long-standing contractual partnership and tireless support related to the IAU's digital functionality.

The IAU's mission is to promote and safeguard astronomy in all its aspects (including research, communication, education and development) through international cooperation.

Science is best advanced when there is mutual trust, respect and integrity, and when it is conducted in environments free from harassment. The IAU expects all members to uphold the IAU Code of Conduct.
