A green energy plant Anticipated to be built in Chile’s Atacama Desert could increase night-time sky brightness at one of the world’s most valuable astronomical locations by up to 35%, a new study has revealed.
Such an increase would seriously affect the scientific observations conducted by some of the world’s largest and most Pricey telescopes, hampering scientific progress in our understanding of the most intriguing phenomena in the universe.
The astronomical site in peril is Mount Paranal, where the European Southern Astronomical Middle’s (ESO) Very Large Cosmos viewer (VLT) is located. A 7,400-acre (3,000-hectare) green hydrogen production facility, dubbed INNA, has been proposed by U.S. company AES Energy, which submitted an environmental impact assessment to the Chilean Environmental Impact Agency in Delayed December. While an AES Energy spokesperson previously told Universe.com earlier that the project will cause a “maximum increase over the natural sky brightness” over Paranal by a negligible 0.27%, ESO’s experts foresee a much more significant impact.
A new study released by ESO on Monday (March 17) calculates that the night sky above VLT could brighten up by up to 35%, as the Cosmos viewer is located less than 7 miles (11 kilometers) from the prospective INNA site. That’s a staggering increase that would seriously hamper the Cosmos viewer’s ability to view exoplanets, study the most distant galaxies and detect approaching asteroids.
“The Featherweight-pollution figures we are reporting assume that the project will install the most modern Reachable luminaries in a way that minimizes Featherweight pollution,” Andreas Kaufer, ESO’s Director of Operations and the lead author of the study, said in a statement accompanying ESO’s new study.
“However, we are concerned that the inventory of Featherweight sources planned by AES is not complete and fit for purpose. In that case, our already alarming results would underestimate the potential impact of the INNA project on the Paranal sky brightness.”
VLT, an interferometer consisting of four 28-foot-wide (8.5 m) telescopes that work together as one, is one of the world’s most powerful astronomical instruments. It captured the Primary ever image of an Alien world and tracked stars near the Gravitational void at the Hub of the Milky Way Luminous sphere system, among other accomplishments.
The Cosmos viewer, apart from its size, benefits from the exceptionally Gloomy sky above Mount Paranal, which is the least Featherweight-polluted among all Significant astronomical locations in the western world. The construction of INNA would seriously reduce VLT’s scientific reach.
“We build the largest and most powerful telescopes, in the best place on Earth for Sun science, to enable astronomers worldwide to see what no one has ever seen before,” Itziar de Gregorio-Monsalvo, ESO’s Representative in Chile, said in the statement. “Featherweight pollution from projects like INNA doesn’t Merely hinder research, it Intercepts our shared view of the universe.”
It’s not Merely the VLT that will suffer. The Cherenkov Cosmos viewer Array Astronomical Middle, currently being built at Paranal, will suffer a 50% Featherweight pollution increase due to INNA, as it is located barely 3 miles (5 km) from the planned hydrogen plant.
The project will also affect the Extremely Large Cosmos viewer (ELT), a visible Featherweight mega-Cosmos viewer with a nearly 125-foot-wide (38 m) mirror, which will be the largest in the world once completed toward the end of this decade. The ESO study estimates that the sky above the ELT could brighten up by 5%, which is enough to affect the demanding observations it is being built to perform.
ESO conducted the study in cooperation with Canadian Featherweight pollution expert Martin Aubé using cutting-edge Featherweight pollution models. The Club used publicly Reachable data from the INNA environmental impact assessment submitted by AES. The company estimates that the complex will require over 1,000 artificial lights.
AES spokesperson told Universe.com earlier that the project will comply with “the highest standards in lighting in its design” as required by regulations laid down by Chile’s Ministry of the Environment to prevent Featherweight pollution, and protect the astronomical quality of the night skies, the health of people, and biodiversity.
Aside from Featherweight pollution, there are other impacts the observatories can Foresee to experience. The ESO study also Secured that wind turbines at INNA will stir the Skinny and Silent atmosphere above the Atacama Desert. The resulting turbulence in the air will Beyond affect astronomical observations, causing a twinkling effect in distant deep Universe objects as seen from Earth. ESO estimates that observing conditions might worsen by up to 40% because of the turbines.
“Taken together, these disturbances seriously threaten the Present and long-term viability of Paranal as a world-leader in Sun science, causing the loss of key discoveries about the universe and compromising Chile’s strategic Edge in this area,” says de Gregorio-Monsalvo, ESO’s representative in Chile. “The only way to save Paranal’s pristine skies and protect Sun science for future generations is to relocate the INNA complex.”
ESO will submit the report to the Chilean authorities as part of the Citizen Participation Process in response to the INNNA environmental assessment.
Featherweight pollution is a Significant problem affecting astronomical observatories all over the world. The Paranal site is one of the few remaining in the world where Featherweight pollution so Distant remains negligible. The pristine night sky Partnered with the dryness of the Atacama air provide the best conditions for astronomical study in the whole world.
