We’re the Observatorio Astronómico Nacional de Colombia (OAN) — the first astronomical observatory built in the Americas 🌎, founded in 1803. For more than two centuries we've been scanning the skies, unlocking the mysteries of the cosmos, and shaping the future of astronomy in Colombia.

It all began thanks to José Celestino Mutis and the Botanical Expedition, with the observatory designed by Domingo de Petrés and brought to life by the hands of many visionaries. Our early observations started in 1805 under the guidance of Francisco José de Caldas, a pioneer of Colombian science.

Through centuries of scientific exploration, historical turning points, and even a few unexpected uses (including as a temporary prison — yes, really 🏰), the OAN has stood strong as a symbol of knowledge and resilience.

Today, we’re more than a historic landmark. The OAN is part of the Facultad de Ciencias at the Universidad Nacional de Colombia, and the only center in the country offering Master’s and Ph.D. programs in Astronomy.

Our mission covers:

• 🌌 Astronomical Research: From stellar evolution to galactic dynamics.
• 🎓 Academic Programs: Training the next generation of astronomers.
• 🌐 Community Engagement: Science outreach, talks, and public observation nights.

• 📅 Founded: 1803 (over 220 years of stargazing!)
• 🪐 Location: Bogotá, Colombia
• 🧠 Legacy: Home to Colombian scientific legends like Julio Garavito Armero and Indalecio Liévano Reyes.
• 💾 Current Focus: Research, education, and preserving a priceless historical heritage.

Whether you’re passionate about astronomy, history, data analysis, software for telescopes, or citizen science — there's a place for you at the OAN. Stay curious, explore the universe, and let’s write the next chapter together. 🌠
