The consortium, which runs the telescope around the world, says that the huge green hydrogen factory proposed for construction in Chile may increase light pollution in one of the world’s most powerful telescopes by at least a third.
ESO analysis released on Monday I found that light pollution would increase by at least 35 % in the very large telescope (VLT)-one of the most advanced visual telescopes in the world-and at least 55 % in the southern matrix of the Tilestalaator Telestaratortatortation (CTAO), which will now be greater than the Building Observatory. The analysis also found that the green energy project will increase the weather disturbances and cause vibrations that would harm sensitive equipment.
Astronomer Easiam de Gregorio Mondeslvo, Aisu in Chile, said at a media conference on Monday that the effects will affect the “destructive, irreversible” damage that cannot be mitigated. “It will reach a point that we will be able to run these telescopes.”
Before the release of the analysis, the developer of the Green Energy Factory, AES Andes in Santiago, said that his project “aims to use the best strict technologies and standards”, and that the company’s analysis found that the project would not have a “great impact” on the notes. On Monday, the company said in a statement, “We are still working to collect data from the ESO document to understand the contradictions between ESO numbers and our own analysis.”
Ideal conditions
The Green Energy Project will extend 3000 hectares in the desert of Chile Atakama, the most dry on Earth. The climate creates a urging and the derivative of the cloud cover there are ideal conditions for stars. The region also contains a very dark sky: a study of 20231 I compared the levels of light pollution in 28 leading astronomical fans around the world and found that the Paranal Observatory, the very large telescope site, had the darkest site for all of them, followed by the nearby Armazone Observatory, where ESO builds the highly large telescope (ELT), which the organization says, “It will be the largest formalization of light and light in the world.”

The dark atacama sky and other attributes attracted organizations to build advanced tools such as VLT and Elt and the southern matrix of CTAO. “Whenever the sky darkens, the astronomical object that can be examined,” notes a summary of the ESO report on the green energy project.
Atacama conditions were also conducted by Energy Company AES ands, a subsidiary of AES Corporation in Arlington, Virginia. The company suggested the use of intense sunlight in the region and strong winds to generate solar energy and wind. This would provide energy to extract hydrogen from water, which can be collected from the near -quiet Ocean. Hydrogen made of renewable energy is often called green hydrogen.
I suggested to building a green hydrogen complex that includes Port and Ammonia and hydrogen production stations, and thousands of electricity generators. The main unit of the project is located 11 km from the Baranal Observatory, 5 km from CTAO and 20 km from ELT.
Fencing numbers
The last analysis of ESO was conducted by Martin Aubé at the Research Center in Astronomical Physics in Quebec in Sherbruck, Canada, who studies light pollution in astronomical facilities, and other researchers led by ESO Andreas Kauer. It relies on the information in the environmental impact report submitted by AES in early January to the Environmental Evaluation Agency in Chile (SEA). The sea will decide whether the AES project is ahead.

ESO analysis found that the increase in artificial light from the AES project will make it difficult for the tools to distinguish between heavenly bodies. “The increase in the brightness of the sky is similar to reducing the size of the telescope mirrors,” said Eduardo Onda Sanza, astronomer at the University of Antovagasta at Chile.
AES Andes results contrast to ESO results. The company said that its accounts showed that the facilities will increase the brightness of the sky by at least 0.27 % in Paranal, 0.09 % in ELT and 0.45 % in CTAO, Luis Saras, the deputy company of the company for the international green hydrogen, wrote in an email to email to email to email to email to email to email to email to email to email to email nature. The company indicated that these numbers fall within the Chilean regulations.
AES was in contact with ESO at all stages of the project until the environmental file was completed, says Sarras. He says that the company continues to include ESO “to participate in lighting design and search for their opinions and analysis results.”
