The world’s darkest observatory, located at Paranal in the Atacama Desert of Chile, is under threat from a massive industrial advancement. The industrial megaproject, planned to be situated just 5 to 11 kilometers from the telescopes at Paranal, poses a notable risk to astronomical observations due to light pollution. This development could cause irreparable damage to the observatory’s ability to conduct precise observations, notably because of the continuous light pollution emitted throughout the project’s operational life.The European Southern Observatory (ESO) has called for the development to be relocated to preserve one of Earth’s last truly pristine dark skies and to safeguard the future of astronomy.ESO director general Xavier Barcons emphasized that the proximity of the AES Andes industrial megaproject to Paranal poses a critical risk to the most pristine night skies on the planet.
Chile’s science minister, Aisen Etcheverry, has acknowledged the importance of both astronomy and energy development. The government has formed a committee to find solutions that allow both activities to coexist, noting that technical and diplomatic efforts are being explored to address the issue.
Paranal Observatory Under Threat: An Interview with Astronomy Expert Dr. Humphreys

In a significant development threatening one of the world’s darkest observatories, the European Southern Observatory (ESO) has raised concerns about an industrial megaproject planned near the paranal Observatory in Chile. This development could severely impact astronomical observations due to light pollution, jeopardizing the future of research at this leading facility.We sat down with Dr. puff Humphreys, a renowned specialist in astronomical observations and light pollution, to discuss the implications and possible solutions.
How Significant is the Threat Posed by the AES Andes Industrial Megaproject?
Dr. Humphreys, could you start by explaining just how critical the Paranal Observatory is for astronomical research?
Absolutely.Paranal Observatory is situated in one of the darkest skies on the planet, making it crucial for observations that require extremely precise measurements. The presence of an industrial megaproject so close poses a major threat to these sensitive observations by introducing significant light pollution.
The Impact of Light Pollution on Research
What kind of impact can light pollution have on observations made at Paranal?
Light pollution disrupts the natural darkness that astronomers rely on to study faint celestial objects. Continuous light pollution from the industrial project can obscure details, reduce the depth of observation, and complicate data interpretation. This, in turn, can prevent critical scientific discoveries and hinder advancements in fields like astrophysics and cosmology.
ESO’s Response and the Call for Relocation
How has the ESO responded to this issue, and what measures are they advocating for?
The ESO has called for the relocation of the AES Andes project to preserve the pristine skies required for high-precision observations. ESO director general Xavier Barcons has emphasized the critical risk that the proximity of this project poses to some of the most pristine night skies on the planet. Relocating would ensure that future generations of astronomers can continue to utilize these invaluable skies.
Solutions for coexistence
Chile’s government has acknowledged the issue and is exploring solutions to allow both activities to coexist. What are your thoughts on the feasibility and effectiveness of such efforts?
Finding a balance between energy development and astronomical research is challenging but possible. Techniques like shielding light sources, using specific types of lighting that minimize pollution, and advanced technological solutions could help. However, these require careful planning and cooperative efforts from both the government and the industrial project.
Concluding Thoughts
Creating a policy framework that protects both scientific endeavors and industrial advancements in Chile is vital. What are the priorities in your view?
The top priority should be the safeguarding of scientific research opportunities. This includes implementing extensive light-pollution mitigation measures and strict regulations. Eig1 importantly, fostering an habitat of open dialogue and collaboration between scientific and industrial stakeholders will be key to finding a sustainable solution.
