Accessible astronomy for everyone

The International Astronomical Union's Office for Astronomy Outreach (OAO) connects the science and discoveries of astronomy with people worldwide. Through global outreach programs and its National Outreach Coordinator network, the OAO fosters a vibrant community passionate about the universe. At the same time, it supports the professional development of astronomers, helping them enhance their science communication skills and bring astronomy closer to society. Together, these efforts aim to inspire curiosity and make astronomy a shared cultural experience.

Build community through public engagement

The OAO is dedicated to bringing astronomy closer to everyone, building bridges between the public and the discoveries of the cosmos. Through interactive projects and global collaborations, we aim to inspire new generations and strengthen the understanding of the universe from an accessible and exciting perspective.

This space is designed for you to easily express your doubts, share your curiosity, and get in touch with an astronomy expert who can guide you. Your voice matters, and we're here to listen.
