Astronomen feiern die Absage eines 10-Milliarden-Dollar-Projekts in Chile, das den klarsten Himmel der Welt bedrohte | Astronomen hatten gewarnt, dass die Nähe der INNA-Anlage zu Teleskopen die Beobachtung irreparabel beeinträchtigt hätte

>The scientific community is celebrating the cancellation of a project which would have [threatened](https://www.theguardian.com/world/2025/mar/04/chile-stargazing-night-sky) the clearest skies in the world in Chile’s Atacama Desert.

>The proposed $10bn, 3,000-hectare green hydrogen and ammonia production facility, known as INNA, included a port, transport links to the coast and three solar power plants, and had been under evaluation by Chile’s environmental regulator for almost a year.

>Astronomers had warned repeatedly that its proximity to some of the world’s most powerful telescopes would have irreparably damaged observation in the area, which is the best site in the world for ground-based astronomy.

>“This cancellation means that the INNA project will no longer have a negative impact on the Paranal Observatory,” said Itziar de Gregorio, the European Southern Observatory’s (ESO) representative in Chile, where it operates three telescope complexes.

>“However, what this megaproject has brought to the table is the urgent need for clear protection measures around the sites where professional astronomy is carried out in Chile. This cancellation does not mean that the work to protect the skies is over.”
