Partner Network

Scientific Collaboration

The International Catalogue of Heavenly Bodies (ICHB) wishes to acknowledge the global network of observatories and research institutions whose dedicated work is the foundation of this project. Building upon a rich heritage of astronomical discovery, our registry reflects the continued dedication of scientists worldwide who meticulously observe, record, and catalogue the heavens.

The ongoing efforts of these institutions in collecting, verifying, and systematizing data on stars, planets, asteroids, and countless other celestial objects are invaluable to our work. This commitment to precision and the longstanding practice of knowledge sharing are essential to our consolidated registry.

We deeply appreciate the established relationships we have with each of these organizations. The very existence of ICHB in its present form is a result of this spirit of active international scientific cooperation and data sharing.

Why This Partnership Matters for ICHB’s Mission

1

Data Preservation

Historical observations from these observatories are digitized and preserved in the ICHB register, ensuring they remain accessible for future generations.

2

Cross-Identification

By linking observations from different eras and institutions, ICHB creates a unified identity for each celestial body across all catalogues.

3

Cultural Heritage

Traditional names from diverse cultures are preserved in both translation and transliteration, respecting linguistic heritage while ensuring global accessibility.

We are particularly grateful to the international community of astronomers and researchers who continue to collaborate with us, ensuring the accuracy and completeness of the data we provide. The ICHB is not merely a catalogue — it is a testament to the power of global scientific cooperation, spanning continents, cultures, and generations.

Every observation, every recorded position, every historical name contributes to a collective understanding of our universe. The observatories listed below represent a fraction of this global effort — each code tells a story of dedication to science.
