Xavier Barcons, Director General of the European Southern Observatory (ESO), said in his statement that astronomers will work with the surroundings of the observatory along with the project. The sky becomes 10 percent brighter He stated that they were waiting for him to arrive. This increase could cause the VLT to lose its status as the world’s most prestigious observatory, making the telescope an “average” observatory.
The energy complex in question is a US energy giant. AES planned by INNA Renewable Energy Park. This project will cover an area of 7,400 acres in Chile’s Atacama Desert. solar power plants, wind turbines and hydrogen production will include facilities. According to ESO’s calculations, this park could emit as much light into the night sky as a city of 20,000 inhabitants.
This project threatens ESO’s $840 million telescope. It will also affect ESO’s new $1.5 billion telescope, the Extremely Large Telescope. Both telescopes were carefully positioned in the most remote areas of the Atacama to take advantage of the planet’s darkest night sky. ESO and its 16 member countries selected the site after an extensive global survey to ensure ideal observing conditions.
Barcons states that ESO is not against the facility, but that building the facility so close poses a problem, and that the problem will be eliminated if the energy complex is built at least 50 kilometers away from the observatory. On the other hand, the renewable energy project is currently at an early stage and awaiting approval.
In recent years, other ground-based observatories such as the VLT have also raised alarms about light pollution. Light pollution does not only occur with the illumination of areas close to these observatories; Increasing density in orbit also poses a problem. It was previously stated that SpaceX’s Starlink satellites affected observations due to brightness. Starlink and other similar satellite constellations, whose numbers are rapidly increasing in orbit, are turning into a bigger problem on this basis.
