MAY-JUNE2025 Potential damages fromINNA“ecological” project confirmed byESO FranciscoRodríguez Bárbara Ferreira nin-depthtechnicalanalysis by the European Southern Observatory(ESO)hasevalu- ated the impact of the INNA megaproject on the facilities at the Paranal Observatory, Chile — and theresultsarealarming.Theanalysis reveals that INNA would increase light pollution above the Very Large Telescope(VLT)byatleast35%and by more than 50% above the south site of the Cherenkov Telescope Array Observatory (CTAO-South). INNA would also increase air turbu- lence in the area, further degrading conditions for astronomical observa- tions,whilevibrationsfromtheproj- ect could seriously impair the functioning of some of the astro- nomicalfacilities,liketheExtremely LargeTelescope(ELT),attheParanal Observatory. In January, ESO publicly raised the alarm about the threat posed to the world’s darkest and clearest skies, those of ESO’s Paranal Observatory, fromtheindustrialmegaproject INNA. The project — by AES Andes, a subsidiary of the US power com- pany AES Corporation — includes multiple energy and processing fa- cilities,spreadoveranareaofmore than 3000 hectares, the size of a smallcity.Itsplannedlocationisjust a few kilometres from the Paranal telescopes. A preliminary analysis done at the time revealed that, due to its size and proximity to Paranal, the INNA project posed significant risks to as- tronomical observations. Now, a de- tailed technical analysis has con- firmed that INNA’s impact would be devastating and irreversible. ﺗﺄﻛ ﺪ اﻷﺿﺮاراﻟﻤﺤﺘﻤﻠﺔ ﻣﻦ ﻣﺸﺮوع INNA " اﻹﻳ ﻮﻟﻮﺟﻲ " ﻓﺮ : ﻘﻠﻢ اﻧﺴ ﺴ ﻮ رودرﻐ و ﺎر ﺮا ﻓ ﺮا اﻟﻤﺮﺻﺪ اﻷوروﺑﻲ اﻟـﺠﻨﻮﺑﻲ أﺟـﺮى ا ﺮﺻﺪ اﻷوروﺑﻲ اﻟﺠﻨـﻮﺑﻲ ﺗﺤﻠـﻴﻼً ﺎً ﺗﻘﻨﻴ ـ ﻣﻌﻤﻘ ًـﺎً ﻟﺘﻘﻴ ـﻴﻢ اﻵﺛــﺎر ا ﺤﺘﻤﻠــﺔ ﴩوع ـ INNA اﻟﻀﺨﻢ ﻣﻨﺸﺂت ﻋﲆ ﻣﺮﺻﺪ ﺑﺎراﻧﺎل ﰲ ﺗﺸﻴﲇ ﻓﻘﺪ ﻛﺸﻔﺖ اﻟﻨﺘـﺎﺋﺞ ﻋـﻦ ﻗﻠﻖ ﺑﺎﻟﻎ ﺣﻴﺚ ﻛﺸﻒ اﻟﺘﺤﻠﻴﻞ أن ا ـﴩوع ﺳﻴﺆدي إﱃ زﻳﺎد ة ﰲ اﻟﺘﻠﻮث اﻟ ﻀـﻮﺋﻲ ﻓـﻮق ﻣﻮﻗﻊ اﻟﺘﻠﺴﻜﻮب اﻟﻌﻤﻼق ﺑﻨﺴﺒﺔ ﻻ ﺗﻘﻞ ﻋﻦ 35% وﺗﺠﺎوز 50 % ﻓﻮق ﻣﺮﺻﺪ ﻣﺼـﻔﻮﻓﺔ ﺗﻠﺴﻜﻮﺑﺎت ﺗﺸـ ﻳﻨﻜﻮف ا ﻮﻗـﻊ اﻟﺠﻨـﻮﺑﻲ ﺗﺸ ﻳﻨﻜﻮف ـــ ) CTAO-South ( ﻋﻼوة ﻋﲆ ذﻟﻚ ﺳﻴﺘﺴـﺒﺐ ﴩوع ﻣـــ INNA ﰲ زﻳــﺎدة اﺿــﻄﺮاﺑﺎت اﻟﻐﻼف اﻟﺠﻮي ﰲ ا ﻨﻄﻘﺔ ﻣﻤـﺎ ﺳـﻴﺆدي إﱃ ﺗﺪﻫﻮر ﻣﻠﺤﻮظ ﰲ ﺟـﻮدة اﻟﺮﺻـﺪ اﻟﻔﻠﻜـﻲ ﺑﺎﻹﺿﺎﻓﺔ إﱃ ذﻟﻚ ﻗـﺪ ﺗُﻀـﻌﻒ اﻻﻫﺘـﺰازات اﻟﻨﺎﺗﺠﺔ ﻋـﻦ ا ﴩـوع ﺑﺸـﻜﻞ ﺧﻄـ أداء ﺑﻌﺾ ا ﺮاﻓﻖ اﻟﺤﺴﺎﺳـﺔ ﻣﺜـﻞ اﻟﺘﻠﺴـﻜﻮب اﻷوروﺑﻲ اﻟﻜﺒ ﻟﻠﻐﺎﻳﺔ ﰲ ﻣﺮﺻـﺪ ﺑﺎراﻧـﺎل . وﻛﺎن ا ﺮﺻـ ﺪ اﻷوروﺑـﻲ اﻟﺠﻨـﻮﺑﻲ ﻗـﺪ دق ﻧﺎﻗﻮس اﻟﺨﻄﺮ ﻋﻠﻨًﺎ ﰲ ﻳﻨﺎﻳﺮ ا ﺎﴈ ﺑﺸـﺄن اﻟﺘﻬﺪﻳﺪ ا ﺘﺰاﻳﺪ اﻟﺬي ﻳﻤﺜﻠﻪ ﻣ ـ ﴩوع INNA اﻟﺼﻨﺎﻋﻲ اﻟﻀﺨﻢ ﻷﻛﺜﺮ ﺳﻤﺎء اﻟﻌﺎﻟﻢ ﻇﻠﻤﺔ وﺻﻔﺎءً وﻫﻲ ﺳﻤﺎء ﻣﺮﺻﺪ ﺑﺎراﻧﺎل اﻟﺘﺎﺑﻊ ﻟﻪ وﻳﺘﻀـﻤﻦ ا ـ ﴩوع ـ اﻟـﺬي ﺗـﺪﻳﺮه ﴍﻛـﺔ AJJJES Corporation ، إﻧﺸﺎء اﻟﻌﺪﻳﺪ AES Andes اﻟﺘﺎﺑﻌــﺔ ﻟﴩــﻛﺔ اﻟﻄﺎﻗــﺔ اﻷﻣﺮﻳﻜﻴﺔ AES Corporation إﻧﺸﺎء اﻟﻌﺪﻳﺪ ﻣﻦ ﻣﺮاﻓﻖ اﻟﻄﺎﻗﺔ وا ﻌﺎﻟﺠﺔ ا ﻤﺘـﺪة ﻋـﲆ ﻣﺴﺎﺣﺔ ﺷﺎﺳﻌﺔ ﺗﺰﻳﺪ ﻋﻦ 3000 ﻫﻜﺘﺎر أي ﻣﺎ ﻳﻌﺎدل ﺣﺠﻢ ﻣﺪﻳﻨﺔ ﺻﻐ ة وﻳﻘﻊ ا ﻮﻗﻊ ا ُﺰﻣﻊ إﻧﺸﺎؤه ﻋﲆ ﺑﻌﺪ ﺑﻀـﻌﺔ ﻛﻴﻠـﻮﻣﱰات ﻓﻘﻂ ﻣﻦ ﺗﻠﺴﻜﻮﺑﺎت ﺑﺎراﻧﺎل . ﻟ ﻘﺪ ﻛﺸﻒ ﺗﺤﻠ ﻴـﻞ أوﱄ أُﺟـﺮي ﰲ ﺣﻴﻨـﻪ أن ـ ﺣﺠﻢ ﻣ ﴩوع INNA وﻗﺮﺑﻪ ﻣـﻦ ﻣﺮﺻـﺪ ﺑﺎراﻧـﺎل ﻳﺸـﻜﻼن ﻣﺨـﺎﻃﺮ ﺟﺴـﻴﻤﺔ ﻋـﲆ ﻋﻤﻠﻴﺎت اﻟﺮﺻﺪ اﻟﻔﻠﻜﻲ واﻵن ﻳﺆﻛـﺪ ﺗﺤﻠﻴـﻞ ﻓﻨﻲ ﻣﻔﺼﻞ أن ﺗﺄﺛ ات ﻣـﴩوع ) INNA ( ﺳﺘﻜﻮن ﻣﺪﻣﺮة وﻻ رﺟﻌﺔ ﻓﻴﻬﺎ ﻋﲆ اﻟﺒﻴﺌـﺔ اﻟﻔﻠﻜﻴﺔ اﻟﻔﺮﻳﺪة ﻟﻠﻤﺮﺻﺪ . ﻣﺎﻳﻮ - ﻳﻮﻧﻴﻮ 2 0 2 5
