- A $10bn green hydrogen and ammonia production facility (INNA) in Chile's Atacama Desert has been canceled.
- Astronomers warned the project would negatively impact observation due to light pollution, vibrations, dust, and atmospheric turbulence.
- The Atacama Desert is considered the best site in the world for ground-based astronomy.
- The cancellation means the INNA project will no longer affect the Paranal Observatory.
- The cancellation underscores the urgent need for clear protection measures around professional astronomy sites in Chile.
- The INNA facility was proposed to be located just 11.6km from the Paranal Observatory, home to the Very Large Telescope (VLT).
