IAU100: Under One Sky

In 2019, the International Astronomical Union (IAU) will celebrate its 100th anniversary. To commemorate this milestone, the IAU will organise a year-long celebration to increase awareness of a century of astronomical discoveries as well as to support and improve the use of astronomy as a tool for education, development and diplomacy under the central theme "Under One Sky".

The centennial celebrations will stimulate worldwide interest in astronomy and science and will reach out to the global astronomical community, national science organisations and societies, policy-makers, students, families and the general public.

The IAU100 activities will take place at global and regional levels, and especially at the national and local levels. To coordinate the initiative, the IAU has set up the IAU100 Task-Force as well as the IAU100 Secretariat.  This taskforce is preparing a comprehensive programme of Flagship initiatives to reach targeted audiences worldwide through the IAU National Outreach Coordinators and National Astronomical Societies, which will set up National IAU100 Task Forces to ensure the worldwide success of the initiative.

Support IAU100 and Make it Happen!

Whether you are a professional working in astronomy, an amateur astronomer or just someone interested in astronomy we would love for everyone to get involved in the celebrations. There are many way you can participate:

Implement one of the endorsed activities locally: for each Flagship, there are several projects being set up that will be implemented by the National IAU100 Committees in different countries. You can help them reach out to as many people as possible in your city.

Develop an activity under one of the Flagship themes: you can also develop your own project following any of the Flagship themes. Just reach out to us with your idea and if it follows the IAU100 Goals we will include in the IAU100 Event Programme. In addition, there will be funding opportunities to support projects developed under Flagship themes.

Implement your own idea: if you have any innovative ideas that you think do not fall under the Flagship themes but still fulfills the IAU100, please don’t hesitate to develop the activity and contact us to include it as part of the IAU100 Event Programme.

Reach out to your National IAU100 Committee: Getting in contact with your IAU100 National Committee is a great opportunity to get the benefit of larger networks, disseminate your event further, share best practices and find out about what will be organized in your country/region.

Spread the word: don't hesitate to spread the word to your colleagues, and perhaps your friends and family outside the community who already understands and appreciates the impact of astronomy in society. The aim is try to and involve everyone, as many of these people might be inspired and go on to organise their own initiatives.

Become an IAU100 Institutional Partner: There are a variety of opportunities for organizations to become IAU100 Institutional Partners. For inquiries about such partnership opportunities, please contact the IAU100 Secretariat.
