nRenewable Energy Project threatens World’s Largest Telescope, Scientists Warn
Scientists have raised alarms over a renewable energy project that could jeopardize the capabilities of the world’s largest telescope. AES Energy, a US-based company, plans to construct a large renewable hydrogen facility in Chile, just a few kilometers from Mount Paranal, home to the European Southern Observatory’s Very Large Telescope (VLT).

Built in the 1990s at a cost of $350 million (equivalent to $840 million today), the Very Large Telescope is one of the world’s most advanced sky-watching instruments. Comprising four 27-foot-wide (8.2 meters) telescopes that work in unison, the high-precision observatory has unraveled some of the universe’s most enigmatic phenomena.
However,its observing capabilities could be drastically reduced if the hydrogen project,INNA,is approved,according to Xavier Barcons,ESO’s Director General,as reported by Space.com.
According to ESO’s analysis, the hydrogen project could increase sky brightness by up to 10%, a change significant enough to downgrade Mount Paranal from one of the world’s premier observatories to an average observing site.This light pollution would hinder the Very Large Telescope’s ability to capture faint astronomical phenomena, diminishing its scientific output, Barcons noted.
Mount Paranal, an 8,740-foot (2,664-meter) peak in Chile’s Atacama Desert, is among the few remaining places on Earth untouched by urban or industrial light pollution.Its location within the Andes mountain range offers a crystal-clear night sky for over 11 months each year, creating ideal conditions for conducting advanced astronomical research.
Mount Paranal’s dark skies Make It the Ideal home for VLT
The VLT owes much of its success to the pristine, dark skies above Mount paranal. A 2023 survey revealed that,among the world’s 28 most advanced astronomical observatories,Mount Paranal experienced the least artificial light pollution.These exceptional conditions also led ESO to select the nearby Mount Armazones for its next-generation telescope, the Extremely Large Telescope (ELT).
Set to become the world’s largest visible-light telescope, the ELT will feature a 130-foot (39.3-meter) mirror and is expected to be operational by the end of this decade, pushing the boundaries of astronomical revelation.
The $1.5 billion telescope is set to build on the legacy of the reliable VLT, offering deeper views of the distant universe and enabling detailed study of possibly habitable exoplanets. However, the anticipated light pollution from the INNA project threatens to undermine these advancements. Increased sky brightness could reduce the ability to observe faint galaxies and compromise efforts to analyze the atmospheres of exoplanets, potentially hindering key scientific discoveries.
ESO estimates that the project could generate light pollution equivalent to a city of 20,000 people. Parts of the industrial park may be as close as 3 miles (5 kilometers) to the telescopes, and any future expansion could worsen the impact on Paranal’s night sky.According to Barcons, while a project like INNA can be relocated to other suitable sites, Mount Paranal remains irreplaceable for astronomers. He emphasized that the two cannot coexist in the same location, suggesting that the hydrogen plant could easily be moved 31 miles (50 kilometers) away without compromising its function.

Renewable Energy vs. Astronomy: Balancing Progress adn Preservation in Chile’s Atacama Desert
In the heart of Chile’s Atacama Desert, a clash between renewable energy development and astronomical research is unfolding. The proposed INNA renewable hydrogen project by AES Energy threatens to increase light pollution near Mount Paranal, home to the European southern Observatory’s (ESO) Very Large Telescope (VLT). Scientists warn that this could substantially hinder the telescope’s ability to observe faint astronomical phenomena, possibly downgrading one of the world’s premier observatories to an average site. to explore this issue further, we spoke with Dr. Elena Morales, an astrophysicist and expert on light pollution’s impact on astronomical research.
The Threat to Mount Paranal’s Pristine Skies
Senior Editor: Dr. Morales, thank you for joining us. Could you start by explaining why Mount Paranal is such a critical location for astronomical research?
Dr. Elena Morales: Absolutely.Mount Paranal is one of the few remaining places on Earth with virtually no light pollution. Its elevation of 8,740 feet in the Atacama Desert, combined with its location within the Andes, provides crystal-clear skies for over 11 months each year. This makes it an ideal site for advanced telescopes like the VLT, which rely on dark skies to capture faint astronomical phenomena.
Senior Editor: How notable is the threat posed by the INNA renewable hydrogen project?
Dr. Elena Morales: The threat is substantial. ESO’s analysis suggests that the project could increase sky brightness by up to 10%. This might sound small, but for astronomical observations, even a slight increase in light pollution can have a dramatic impact. It could reduce the VLT’s ability to observe faint galaxies and exoplanets, effectively downgrading Mount Paranal from a world-class observatory to an average site.
The Impact on the Very Large Telescope and Beyond
Senior Editor: The VLT has been instrumental in many groundbreaking discoveries.Could you elaborate on how its capabilities might be affected?
Dr. Elena Morales: The VLT is a marvel of modern astronomy. Its four 27-foot-wide telescopes work in unison to study everything from black holes to the atmospheres of distant exoplanets. Increased light pollution would make it harder to observe faint objects, which are frequently enough the most scientifically valuable. Such as,studying the atmospheres of potentially habitable exoplanets requires extremely precise measurements that could be compromised by even a small increase in sky brightness.
Senior Editor: What about the future Extremely Large Telescope (ELT)? How might this project affect its operations?
Dr. Elena Morales: The ELT, set to become the world’s largest visible-light telescope, is also located nearby on Mount Armazones. Its 130-foot mirror will push the boundaries of astronomical discovery, but it will be equally vulnerable to light pollution. If the INNA project goes ahead as planned, it could undermine the ELT’s ability to achieve its scientific goals, such as studying the early universe and identifying habitable exoplanets.
Finding a Balance: renewable Energy and Astronomy
Senior Editor: Renewable energy is crucial for combating climate change. Is there a way to balance these competing priorities?
Dr. Elena Morales: Absolutely. Renewable energy is essential, but it doesn’t have to come at the expense of astronomy. ESO has proposed relocating the INNA project just 31 miles (50 kilometers) away, which would minimize its impact on Mount Paranal while still allowing the project to proceed. This kind of compromise is achievable and necessary to protect both our planet and our ability to explore the universe.
Senior Editor: What would you say to those who argue that the economic benefits of the INNA project outweigh the potential harm to astronomy?
Dr. Elena Morales: While the economic benefits of renewable energy are undeniable,we must also consider the long-term value of astronomical research. Discoveries made at Mount Paranal have deepened our understanding of the universe and our place within it. these are not just scientific achievements; they inspire humanity and drive technological innovation. We can’t afford to loose such a unique resource.
Key Takeaways
- Mount Paranal’s Importance: Its pristine skies make it one of the best locations for astronomical research.
- Impact of Light Pollution: A 10% increase in sky brightness could significantly reduce the VLT’s capabilities.
- Proposed Solution: Relocating the INNA project 31 miles away could protect both renewable energy goals and astronomical research.
