Historic observatories are the places where modern astronomy was born and our understanding of the universe emerged to be sites of awe and discovery.
Members of the Alliance of Historic Observatories thrive as robust institutions that inspire awe, contribute to advancing astronomical discovery, and carry out our missions.
The Alliance of Historic Observatories (AHO) acts as a vehicle for global collaboration in research, inspiration and engagement, and preservation of historical resources.
Develop strategies for preserving and sharing our legacies with future generations.
Share methods to preserve the infrastructure of historic observatories.
Tell our stories as a model for how the observatories inspire people around the world to foster greater literacy in science.
Become model institutions of youth STEM programs.
The AHO was established in 2019 as a group of scientifically and historically prominent observatories gathered to consider their future.
AHO observatories meet every fall, typically for a couple of days, to discuss and plan alliance matters, exchange ideas, share experiences, and celebrate the achievements of our members. Yerkes Observatory will host the next meeting on 5 - 7 October, 2023.
