A proposed industrial megaproject near the European southern observatory’s Paranal Observatory in the Atacama Desert, Chile, is causing concern due to potential light pollution. Paranal Observatory is home to the Vrey Large Telescope (VLT), one of the world’s premier astronomical instruments, renowned for its ability to observe the cosmos in dark skies.
Several studies and reports highlight the threat to the observatory’s operations. A 2023 study published in Monthly Notices of the Royal Astronomical Society shows that Paranal Observatory is one of the darkest sites among major astronomical observatories globally, making it particularly vulnerable to light pollution [2[2[2[2].
The industrial project, which includes a proposed factory, is estimated to be within 11 km of the observatory, much closer than the company’s own estimate of 20 to 30 km.Researchers are calling for the creation of a “light exclusion zone” to protect the integrity of the site [1[1[1[1].
The company behind the project, AES ANDES, has assured that it adheres to the highest standards of lighting as mandated by the government. This regulation aims to protect key astronomical observation sites. However, the project is currently under environmental assessment and is not expected to receive its operating license for another two to three years [3[3[3[3].
Additionally, there are concerns that the energy megaproject could interfere with the operation of the European Extremely Large Telescope (E-ELT), currently under construction about 20 kilometers away. The E-ELT, with a 39-meter diameter, is set to be the largest optical telescope in the world and is scheduled for launch in 2028. Astronomers worry that increased light pollution could delay meaningful scientific discoveries, including answers to basic questions about the universe [3[3[3[3].
the proposed industrial megaproject poses a significant threat to the dark skies essential for astronomical research at Paranal Observatory and the upcoming E-ELT, perhaps hindering future scientific advancements.

Editor: Can you explain the current status of the Industrial Megaproject and its expected timeline for operation?
Guest: The industrial megaproject is currently undergoing an environmental assessment. This process is critical to ensure that the project’s impact on the surrounding habitat is minimal. However, it is not expected to receive its operating license for another two to three years. This delay allows for thorough assessment and proposed modifications to mitigate any negative effects.
Editor: What are the specific concerns regarding the European Extremely Large Telescope (E-ELT) and the industrial megaproject?
Guest: The main concern is the potential interference with the operation of the European Extremely Large Telescope (E-ELT), which is currently under construction approximately 20 kilometers away. the E-ELT, with its 39-meter diameter, is set to become the largest optical telescope in the world and is scheduled for launch in 2028. Astronomers have expressed worry that increased light pollution from the industrial megaproject could severely impede meaningful scientific discoveries. This includes delaying answers to fundamental questions about the universe.
Editor: How does the proposed industrial megaproject threaten the dark skies essential for astronomical research?
Guest: The industrial megaproject poses a significant threat to the dark skies essential for astronomical research at both the Paranal Observatory and the upcoming E-ELT.Dark skies are crucial for capturing detailed observations of celestial bodies, and any increase in light pollution can hinder these observations. This may lead to delayed or missed scientific advancements, making it challenging to answer pressing questions about the universe.
Editor: What potential scientific advancements could be hindered by this light pollution?
Guest: The potential scientific advancements that could be hindered are vast. Astronomers are concerned about delays in discovering exoplanets, understanding the formation of galaxies, and exploring the early universe. Light pollution can obscure faint celestial objects, making it difficult to gather accurate data and draw meaningful conclusions. This would possibly set back research on some of the most profound questions in cosmology and astrophysics.
Editor: Are there any plans or measures in place to mitigate the impact of this industrial megaproject on the E-ELT?
Guest: While environmental assessments are ongoing, specific mitigation measures have yet to be fully defined. However, stakeholders are actively engaged in discussions to find solutions that balance the industrial development with the need to preserve dark skies for astronomical research. It is crucial to find a way to minimize light pollution and ensure the E-ELT’s scientific objectives are not compromised.
Conclusion:
The industrial megaproject, while significant for economic development, threatens the critical dark skies required for astronomical research at both the Paranal Observatory and the upcoming E-ELT. Increased light pollution could delay vital scientific discoveries and inhibit our understanding of the universe. Stakeholders must collaborate to implement effective mitigation measures before the project receives its operating license.
