The striking launch of these lasers, one from eachoftheeight-metretelescopes at Paranal, is a significant milestone oftheGRAVITY+project—alarge and complex upgrade to ESO’s Very Large Telescope Interferometer (VLTI). GRAVITY+ unlocks a greater observing power and a much wider sky coverage for the VLTI than pre- viously possible. “This is a very im- portant milestone for a facility that iscompletelyuniqueintheworld,” ﺗﺠﺮ ﺔ ﻟ رﺗﻤﻬﺪ ﻟـﺤﻘ ﺔ ﺟﺪ ﺪة ﻓﻲﻋﻠﻢ اﻟﺘﺪاﺧﻞ : ﻘﻠﻢ ﺎر ﺮا ﻓ ﺮا اﻟﻤﺮﺻﺪ اﻷوروﺑﻲ اﻟـﺠﻨﻮﺑﻲ أﻃﻠﻘـﺖ أرﺑﻌ ﺔ أﺷـﻌﺔ ﻟﻴـﺰر ﻧ ﺤـﻮ ﺳـﻤﺎء ﻣﺮﺻﺪ ﺑﺎراﻧﺎل اﻟﺘـﺎﺑﻊ ﻟ ﻠﻤﺮﺻـﺪ اﻷوروﺑـﻲ اﻟﺠﻨﻮﺑﻲ ﰲ ﺗﺸﻴﲇ ﺗو ﺴﺘﺨﺪم ﻛﻞ ﺣﺰﻣﺔ ﻟﻴﺰر ﻻﻧﺸـﺎء ﻧﺠـﻢ ﻹﻧﺸـﺎء ﻧﺠـﻢ اﺻـﻄﻨﺎﻋﻲ، ﻳﺴﺘﻌ ﺑﻪ ﻋﻠﻤﺎء اﻟﻔﻠﻚ ﰲ ﻗﻴـﺎس اﻟﺘﺸـﻮّه ﻻﻧﺸﺎء ﻧﺠﻢ اﺻﻄﻨﺎﻋﻲ ﻳﺴﺎﻋﺪ ﻋﻠﻤﺎء اﻟﻔﻠﻚ ﻋﲆ ﻗﻴﺎس ﺗﺸﻮه اﻟﻀﻮء اﻟﻨﺎﺗﺞ ﻋﻦ ا ﻟﻐـﻼف اﻟﺠﻮي ﻟﻸرض ﺛـﻢ ﺗ ﺪ ﻌـ ﺼـﺤﻴﺤﻪ وﻳ ﻫـﺬا اﻹﻃﻼق ا ﺘﺰاﻣﻦ ﻣﻦ ﻛﻞ ﺗﻠﺴﻜﻮب ذي ﻗﻄﺮ 8 أﻣﺘﺎر ﰲ ﺑﺎراﻧﺎل ﺧﻄﻮة ﻣﻔﺼﻠﻴﺔ ﻣﻬﻤﺔ ﰲ ـﻣ ﻏﺮاﻓﻴﺘـﻲ ﴩوع + وﻫـﻮ ﺗﺤـﺪﻳﺚ ﻛﺒـ وﻣﻌﻘّﺪ ﻨﻈﻮﻣﺔ ﻣﻘﻴﺎس اﻟﺘﺪاﺧﻞ ﻟﻠﺘﻠﺴﻜﻮب اﻟﻜﺒ ﺟﺪاً ﻟﺘﺪاﺧﻞ ﻟﻠﺘﻠﺴﻜﻮب اﻟﻜﺒـ ﺟـﺪًا اﻟﻜﺒ ﺟﺪ ﻮﻓﺮ ﻳ .اً ﻣﴩوع ﻏﺮاﻓﻴﺘﻲ + ﻗـﺪرة رﺻﺪ أﻋﲆ ﺑﻜﺜ اﱃ ﺟﺎﻧﺐ ﺗﻮﺳـﻴﻊ ﻣﺠـﺎل اﻟﺴـﻤﺎء اﻟـﺬي ﻳﻤﻜـﻦ ﻟ ﻠﻤﻨﻈﻮﻣـﺔ رﺻـﺪه ﻣﻘﺎرﻧﺔ ﺑﻤﺎ ﻛـﺎن ﻣﺘﺎﺣـ ﺎً ﻳﻘـﻮل و . ﺎً ﺳـﺎﺑﻘ أﻧﻄ ـﻮان ﻣ ـ ان ﻋ ـﺎﻟﻢ اﻟﻔﻠ ـﻚ ﰲ ا ﺮﺻ ـﺪ اﻷوروﺑﻲ اﻟﺠﻨﻮﺑﻲ وا ﺴـﺌﻮل اﻟﻌﻠﻤـﻲ ﻋـﻦ ﺑﺮﻧﺎﻣﺞ ﻣﻘﻴـﺎس اﻟﺘـﺪاﺧﻞ :» ﺗﻤﺜـﻞ ﻫـﺬه ﻣﺤﻄﺔ ﺑﺎﻟﻐﺔ اﻷﻫﻤﻴﺔ ﻨﺸـﺄة ﻓﺮﻳـﺪة ﻣـﻦ - ﻳﻨﺎﻳﺮ ﻓﺒﺮﺍﻳﺮ 2 0 2 6
