“The extreme environment of the galacticcenterisafascinatingplace toputstarformationtheoriestothe test,andtheinfraredcapabilitiesof NASA’sJamesWebbSpaceTelescope providetheopportunitytobuildon past important observations from ground-basedtelescopeslikeALMA andMeerKAT,” saidSamuelCrowe, another principal investigator on the research, a senior undergradu- ateattheUniversityofVirginiaand a 2025 Rhodes Scholar. Bally and Croweeachledapaperpublishedin The Astrophysical Journal . In Sagittarius C’s brightest cluster, theresearchersconfirmedthetenta- tivefindingfromtheAtacamaLarge Millimeter Array (ALMA) that two massive stars are forming there. Alongwithinfrareddata from NASA’s retired SpitzerSpaceTelescope andSOFIA(Stratospheric ObservatoryforInfrared Astronomy) mission, as well as the Herschel SpaceObservatory,they usedWebbtodetermine thateachofthemassive protostars is already more than 20 times the mass of the Sun. Webb alsorevealedthebright outflowspoweredby Even more challenging is finding low-mass protostars, still shrouded in cocoons of cosmic dust. Re- searchers compared Webb’s data with ALMA’s past observations to identify five likely low-mass proto- star candidates. The team also identified 88 features that appear to be shocked hydro- gen gas, where material being blastedoutinjetsfromyoungstars impacts the surrounding gas cloud. Analysisofthesefeaturesledtothe discovery of a new star-forming cloud,distinctfromthemainSagit- tariusCcloud,hostingatleasttwo protostarspoweringtheirownjets. “Outflowsfromformingstarsin Sagittarius C have been hinted at in past observations, but this is the first time we’ve been able to con- firmthemininfraredlight.It’svery excitingtosee,becausethereisstill a lot we don’t know about star for- mation, especially in the Central Molecular Zone, and it’s so impor- tant to how the universe works,” said Crowe. Webb’s 2023 image of Sagittarius C showeddozensofdistinctivefila- ments in a region of hot hydrogenplasma surrounding the main star-forming cloud. New analysis by Bally andhisteamhasledthemtohy- pothesizethatthefilamentsare shapedbymagneticfields,which have also been observed in the past by the ground-based observatories ALMAandMeerKAT(formerlythe Karoo Array Telescope). “The mo-tion of gas swirling in the extreme tidal forces of the Milky Way’s su- permassiveblackhole,Sagittarius A*,canstretchandamplifythesurround ing magnetic fields. Those fields,inturn,areshapingtheplasma in Sagittarius C,” said Bally. The researchers think that the mag- neticforcesinthegalacticcenter may be strong enough to keep theplasma from spreading, instead con- fining it into the concen- trated filaments seen in the Webb image. These strong magnetic fields may also resist the gravity that would typi- callycausedensecloudsof gas and dust to collapse andforgestars,explaining SagittariusC’slower-than- expected star formation rate. “This is an exciting areaforfutureresearch,as the influence of strong magneticfields,inthecen- terofourgalaxyorother galaxies,onstellarecology has not been fully consid- eachprotostar. ered,” saidCrowe.     ﻣﺠﻠﺔ FreeAstronomy ﺎﻟﻌﺮ ﺔ 15 ﺗـﻮﻓﺮ اﻟﺼــﻔﺤﺔ اﻟﺴــﺎ ﻘﺔ ــﺎسﺳــ ﺎﻗًﺎ ﻟﺼــﻮرﺗﻠﺴــ ﻮﺑﻲ اﻟﻌﻼﻣـﺎت وأﺳـﻬﻢ اﻟﺒﻮﺻــﻠﺔ وأﺷـﺮﻃﺔ اﻟﻤﻘ ـــﺐ اﻟﻔﻀــــﺎﺋﻴ ـــﺎت وﺟــــ ﻤﺲو ﻣ . ﺗﻘـــﻊ ﻣﻨﻄﻘــــﺔ ـــﻮﻳﻦ ﺗ اﻟﻨﺠــــﻮم " ﺳـــﺎﺟ ﺘﺎر ﻮس c" اﻟﺘﻘﻄﻬــــﺎ اﻟــــ ــــﺐ اﻟﻔﻀــــﺎﺋﻲ، ﻋﻠــــﻰ ﺗﻠﺴــــ ﻮبﺟــــ ﻤﺲو ﻣﺴــــﺎﻓﺔ ﺣــــﻮاﻟﻲ 200 ﺳــــﻨﺔ ﺿــــﻮﺋ ﺔ ﻣــــﻦ اﻟﺜﻘــــﺐ اﻷﺳـــــﻮد ا ﻟﻬﺎﺋــــﻞ ﻓـــــﻲﻣﺮﻛــــﺰﻣﺠـــــﺮة در اﻟﺘ ﺎﻧــــﺔ " ﺳـــــﺎﺟ ﺘﺎر ﻮس A ."* ـــــﺔ ـــــﻞ اﻟـــــﺨ ﻄ ﺔ اﻟﻌﻤﻮد ﺗﺤــــﺎﻛﻲ اﻟﻬ ﺎ اﻟﺘﻘﻄﻬﺎ ﺗﻠﺴ ﻮب و ﺐ ﻋﻠﻰ ﻧﻄﺎق أﺻـﻐﺮﻓـﻲ اﻷﺷـﻌﺔ اﻟﻀ ﻤﺔ ﻓﻲ ﺑ ﺎﻧﺎت رادﻳﻮ ﻣ ﺎت ﺗﻠﻚ اﻟ زرﻗــــــــﺎء ﻣﺨﻀــــــــﺮة ــــــــﺪروﺟ ﺗﺤــــــــﺖ اﻟـــــــــ ﻤﺮاء ﻓــــــــﻲﺳـــــــــﺤﺎ ﺔ ﻫ . ﻌﺘﻘـــــــــﺪ ﻋﻠﻤــــــــﺎء اﻟﻔﻠــــــــﻚ أن اﻟﻤﺠـــــــــﺎﻻت اﻟﻤﻐﻨﺎ ــ ﻃ ﺴـ ﺔ اﻟﻘﻮ ﺔ ﻓــﻲﻗﻠــﺐ اﻟﻤﺠـﺮة ﺗﺸــ ﻞ ﻫــﺬﻩ اﻟــ ـ . ﺨﻴﻮط ﺗـﻢ ﺗﺨﺼــ ﺺاﻟﻤﺆﺷـﺮاﻟﻄ ﻔــﻲﻓـﻲ أﺳﻔﻞ اﻟ ﺴـﺎر ) ( ﻈﻬـﺮﻟﻮﻧـﺎً ﻟﺒ ﺎﻧـﺎت اﻟﺮادﻳـﻮ ﻹﻧﺸـﺎء اﻟﺼـﻮرة . ـ ﻋﻠـﻰ اﻟـ ﺠﺎﻧﺐ اﻟﺴـﺎﻟﺐ ﻳﻮﺟـﺪ اﻧ ﻌـﺎث ﻏـ ﺣــﺮاري ﺗـــﺪورﺣـــﻮل ﺧﻄــﻮط اﻟﻤﺠـــﺎل اﻟ ﻣﺤﻔَــﺰﺑﻮاﺳــﻄﺔ اﻹﻟﻜ وﻧـــﺎت اﻟــ ﻤﻐﻨﺎﻃ ﺴــﻲ . ـــﺔ ﻣـــﻦ اﻟﻨﺎﺣ ـــﺔ اﻹﻳﺠﺎﺑ ﺼـــﺪراﻻﻧ ﻌـــﺎث ا ـﻟـــ ﺤﺮاريﻣـــﻦ اﻟ ﻼزﻣـــﺎ اﻟﺴـــﺎﺧﻨﺔ اﻟﻤﺘﺄ ﻨـــﺔ . ـــﺐ ﺎﻟﻨﺴـــ ﺔ ﻟﺘﻠ ﺴـــ ﻮب و ﺪد ﺤـــ ﻳ اﻟﻠﻮن ﺘﺤﻮﻳﻞ ﻃ ﻒ اﻷﺷﻌﺔ ﺗﺤﺖ اﻟ ـ ﻤﺮاء إﻟـﻰ أﻟـﻮان اﻟﻀـﻮء اﻟﻤﺮ ـﻲ . أﻗﺼـﺮأﻃـﻮال ﻣﻮﺟـﺎت اﻷﺷـﻌﺔ ﺗﺤﺖ اﻟ ـ ﻤﺮاء ﺗ ﻮن أﻛ زرﻗﺔ واﻷﻃﻮال اﻟﻤﻮﺟ ﺔ اﻷﻃﻮل ﺗ ﺪو أﻛ ا ﻤﺮارا . ﻗﺎل ﺻﺎﻣﻮﻳﻞ ﻛﺮو وﻫﻮ ﺑﺎﺣﺚ رﺋﻴ ـ ﴘ آﺧـﺮ ﺤﺚ ﰲ اﻟﺒ وﻃﺎﻟﺐ ﺟﺎﻣﻌﻲ ﰲ ﺟﺎﻣﻌﺔ ﻓﺮﺟﻴﻨﻴﺎ وﺣﺎﺻﻞ ﻋﲆ ﻣﻨﺤﺔ رودس ﻟﻌﺎم 2025 ": ﺗﻌﺪ اﻟﺒﻴﺌﺔ ا ﺘﻄﺮﻓﺔ ﺮﻛـﺰ ا ﺠـﺮة ﻣﻜﺎﻧـﺎَ ﺎً راﺋﻌـ ﻻﺧﺘﺒﺎر ﻧﻈﺮﻳﺎت ﺗﻜﻮّن اﻟﻨﺠﻮم وﺗﺘﻴﺢ ﻗﺪرات ﺗﻠﺴﻜﻮب ﺟﻴﻤﺲ وﻳﺐ اﻟﻔﻀﺎﺋﻲ اﻟﺘﺎﺑﻊ ﻟﻨﺎﺳﺎ ﰲ ﻣﺠﺎل اﻷﺷﻌﺔ ﺗﺤﺖ اﻟﺤﻤﺮاء ﻓﺮﺻﺔً ﻟﺒﻨـﺎء أرﺻﺎدٍ ﻣﻬﻤﺔ ﺳﺎﺑﻘﺔ ﻣﻦ ﺗﻠﺴﻜﻮﺑﺎت أرﺿـﻴﺔ ﻣﺜﻞ ﻣﺮﺻﺪ أ ﺎ و ﻣ ﻛﺎت وﻗﺪ ﻧﴩ ﻛـﻞ ﻣـﻦ ﺑﺎﱄ وﻛﺮو ورﻗـﺔ ﺑﺤﺜﻴـﺔً ﰲ ﻣﺠﻠـﺔ اﻟﻔﻴﺰﻳـﺎء اﻟﻔﻠﻜﻴـــﺔ . ﰲ أ ـــﻊ ﻋﻨﻘـــﻮد ﰲ ﻣﻨﻄﻘـــﺔ ﺳﺎﺟﻴﺘﺎرﻳﻮس C أﻛﺪ اﻟﺒﺎﺣﺜﻮن اﻟﻨﺘﺎﺋﺞ اﻷوﻟﻴﺔ ﻣﻦ ﻣﺼﻔﻮﻓﺔ أﺗﺎﻛﺎﻣﺎ ا ﻠﻴﻤﱰﻳﺔ اﻟﻜﺒ ة أ ﺎ) ( اﻟﺘﻲ ﺗﺸ إﱃ ﺗﻜﻮ ﻳ ﻦ ﻧﺠﻤ ﺿﺨﻤ ﻫﻨـﺎك . إﱃ ﺟﺎﻧﺐ ﺑﻴﺎﻧﺎت اﻷﺷﻌﺔ ﺗﺤﺖ اﻟﺤﻤـﺮاء ﻣـﻦ ﺗﻠﺴﻜﻮب ﺳﺒﻴﺘﺰر اﻟﻔﻀﺎﺋﻲ ا ُﺘﻘﺎﻋـﺪ اﻟﺘـﺎﺑﻊ ﻟﻨﺎﺳﺎ وﻣﻬﻤ )ﺔ ( ﺻﻮﻓﻴﺎ ﻣﺮﺻﺪ اﻟﺴﱰاﺗﻮﺳﻔ ﻟﻌﻠﻢ اﻟﻔﻠﻚ ﺑﺎﻷﺷﻌﺔ ﺗﺤﺖ اﻟﺤﻤﺮاء ( ﺑﺎﻹﺿﺎﻓﺔ إﱃ ﻣﺮﺻــﺪ ﻫ ﺷــﻞ اﻟﻔﻀــﺎﺋﻲ اﺳــﺘﺨﺪم اﻟﺒﺎﺣﺜﻮن ﺗﻠﺴﻜﻮب وﻳﺐ ﻟﺘﺤﺪﻳﺪ أن ﻛﺘﻠﺔ ﻛـﻞ ﻧﺠﻢ أوﱄ ﺿﺨﻢ ﺗﺰﻳـﺪ ﻋـﻦ 20 ﺿـﻌﻒ ﻛﺘﻠـﺔ اﻟﺸﻤﺲ . ﻛﻤـﺎ ﻛﺸـﻒ ﺗﻠﺴـﻜﻮب وﻳـﺐ ﻋـﻦ اﻟﺘﺪﻓﻘﺎت اﻟﺴﺎﻃﻌﺔ اﻟﺘﻲ ﻳﻐﺬﻳﻬﺎ ﻛﻞ ﻧﺠﻢ أوﱄ واﻷﺻﻌﺐ ﻣﻦ ذﻟﻚ ﻫﻮ اﻟﻌﺜﻮر ﻋﲆ ﻧﺠﻮم أوﻟﻴﺔ ﻣﻨﺨﻔﻀﺔ اﻟﻜﺘﻠﺔ، ﻻ ﺗﺰال ﻣ ﺤﺎﻃﺔ ﺑﻄﺒﻘﺔ ﻣﻦ اﻟﻐﺒﺎر اﻟﻜﻮﻧﻲ . ﻟﻘﺪ ﻗﺎرن اﻟﺒـﺎﺣﺜﻮن ﺑﻴﺎﻧـﺎت ﺗﻠﺴﻜﻮب وﻳﺐ ﺑﺒﻴﺎﻧﺎت ﻣﺮﺻﺪ أ ـﺎ اﻟﺴـﺎﺑﻘﺔ ﻟﺘﺤﺪﻳﺪ ﺧﻤﺴﺔ اﺟﺮام ﻣﺤﺘﻤﻠﺔ ﻛ ﻨﺠﻮم أوﻟﻴـﺔ ﻣﻨﺨﻔﻀﺔ اﻟ . ﻜﺘﻠﺔ ﻛﻤﺎ ﺣﺪد اﻟﻔﺮﻳﻖ ٨٨ ﺳﻤﺔ ــﺔ اﻟﻜﺘﻠــﺔ . ﻛﻤ ـﺎ ﺣ ـﺪد اﻟﻔﺮﻳــﻖ 88 ﻣﻴــﺰة ﺗﺒــﺪو وﻗــﺪ ﺑ ﺻﺪﻣﺖ ﻐﺎز ﻫﻴـﺪروﺟ ﺣﻴـﺚ ﺗﺼـﻄﺪم ا ـﻮاد ا ُﻨﻄﻠﻘ ـﺔ ﻣ ـﻦ اﻟﻨﺠﻮم اﻟﻔﺘﻴـﺔ ﺑﺴـﺤﺎﺑﺔ اﻟﻐـﺎز ا ﺤﻴﻄــﺔ . أدى ﺗﺤﻠﻴ ــﻞ ﻫـــﺬه اﻟﺴـﻤﺎت إﱃ ا ﻛﺘﺸــﺎف ﺳ ـﺤﺎﺑﺔ ﺟﺪﻳﺪة ﻟﺘﻜﻮﻳﻦ اﻟﻨﺠﻮم ﻣﻨﻔﺼـﻠﺔ ﻋـﻦ ﺳـﺤﺎﺑﺔ ﺳـﺎﺟﻴﺘﺎرﻳﻮس C اﻟﺮﺋﻴﺴــﻴﺔ ﺗﺴﺘﻀــﻴﻒ ﻧﺠﻤــ أوﻟﻴــ ﻋــﲆ اﻷﻗــﻞ ﻳ ﻐــﺬﻳﺎن ﻧﻔﺎﺛﺎﺗﻬﻤﺎ . ﻗﺎل ﻛﺮو " : ﻟﻘﺪ أ ُﺢ إﱃ ﺗﺪﻓﻘﺎت ﻣﻦ اﻟﻨﺠﻮم ا ﺘﺸـﻜﻠﺔ ﰲ ﺳــﺤﺎﺑﺔ ﺳــﺎﺟﻴﺘﺎرﻳﻮس C ﰲ ﻋﻤﻠﻴﺎت رﺻﺪ ﺳﺎﺑﻘﺔ ﻟﻜـﻦ ﻫـﺬه ﻫﻲ ا ﺮة اﻷوﱃ اﻟﺘﻲ ﻧﺘﻤﻜﻦ ﻓﻴﻬـﺎ ﻣ ـﻦ ﺗﺄﻛﻴ ـﺪ وﺟﻮدﻫ ـﺎ ﰲ ﺿ ـﻮء ﻣﻦ ﺗﺄﻛﻴﺪ وﺟﻮدﻫـﺎ ﰲ ﺿـﻮء اﻷﺷـﻌﺔ ﺗﺤـﺖ اﻟﺤﻤﺮاء ﻣ. ﻦ ا ﺜ ﻟﻼﻫﺘﻤﺎم ﻟﻠﻐﺎﻳـﺔ رؤﻳﺘﻬـﺎ ﻷﻧﻪ ﻻ ﻳﺰال ﻫﻨﺎك ا ﻟﻜﺜـ ﻣﻤـﺎ ﻧﺠﻬﻠـﻪ ﻋـﻦ ﺗﻜﻮﻳﻦ اﻟﻨﺠﻮم وﺧﺎ ﺻﺔ ﰲ ا ﻨﻄﻘﺔ اﻟﺠﺰﻳﺌﻴـﺔ ا ﺮﻛﺰﻳﺔ وﻫﻮ أﻣﺮ ﺑﺎﻟﻎ اﻷﻫﻤﻴﺔ ﻟﻜﻴﻔﻴﺔ ﻋﻤـﻞ اﻟﻜﻮن ." أﻇﻬﺮت ﺻـﻮرة وﻳـﺐ ﻟﻌـﺎم 2023 ﻟﺴﺤﺎﺑﺔ ﺳﺎﺟﻴﺘﺎرﻳﻮس C ـﻋ ﴩات اﻟﺨﻴـﻮط ا ﻤ ﻴﺰة ﰲ ﻣﻨﻄﻘﺔ ﻣـﻦ ﺑﻼزﻣـﺎ اﻟﻬﻴـﺪروﺟ اﻟﺴﺎﺧﻨﺔ ا ﺤﻴﻄﺔ ﺑﺴﺤﺎﺑﺔ ﺗﻜـﻮﻳﻦ اﻟﻨﺠـﻮم اﻟﺮﺋﻴﺴﻴﺔ . دﻓﻌﻬﻢ ﺗﺤﻠﻴﻞ ﺟﺪﻳـﺪ أﺟـﺮاه ﺑـﺎﱄ وﻓﺮﻳﻘﻪ إﱃ اﻓﱰاض أن اﻟﺨﻴﻮط ﺗﺘﺸﻜﻞ ﺑﻔﻌﻞ ا ﺠﺎﻻت ا ﻐﻨﺎﻃﻴﺴﻴﺔ واﻟﺘﻲ رﺻـﺪت ﺳـﺎﺑﻘ ﺎً أﻳﻀًﺎ ﺑﻮاﺳـﻄﺔ ا ﺮاﺻـﺪ اﻷرﺿـﻴﺔ ﻣﺜـﻞ أ ـﺎ وﻣ ﻛﺎت ا ﻌﺮوف ﺳﺎﺑﻘًﺎ ﺑﺎﺳـﻢ ﺗﻠﺴـ ) ﻜﻮب ﻣﺼـﻔﻮﻓﺔ ( ﻛـﺎرو وﴏح ﺑـﺎﱄ " : إن ﺣﺮﻛـﺔ اﻟﻐــــﺎز اﻟــــﺪواﻣﻲ ﰲ ﻗــــﻮى ا ــــﺪ اﻟﻐﺎز اﻟﺪواﻣﻲ ﰲ ﻗﻮى ا ﺪ واﻟﺠـﺰر ا ﻟﺸـﺪﻳﺪة ﻟﻠﺜﻘﺐ اﻷﺳﻮد اﻟﻬﺎﺋﻞ ﰲ ﻣﺠـﺮة درب اﻟﺘﺒﺎﻧـﺔ ﺳﺎﺟﻴﺘﺎرﻳﻮس * A ﻳﻤﻜـﻦ أن ﺗُﻤـﺪد وﺗُﻀـﺨّ ﻢ ا ﺠﺎﻻت ا ﻐﻨﺎﻃﻴﺴﻴﺔ ا ﺤﻴﻄﺔ وﻫﺬه ا ﺠﺎﻻت ﺑﺪورﻫﺎ ﺗﺸﻜ ﻞ اﻟﺒﻼزﻣـﺎ ﰲ ﻣﻨﻄﻘـﺔ ﺗﻜـﻮﻳﻦ اﻟﻨﺠﻮم ﺳﺎﺟﻴﺘﺎرﻳﻮس C . ﻳﻌﺘﻘﺪ اﻟﺒﺎﺣﺜﻮن أن اﻟﻘـﻮى ا ﻐﻨﺎﻃﻴﺴـﻴﺔ ﰲ ﻣﺮﻛﺰ ا ﺠﺮة ﻗﺪ ﺗﻜﻮن ﻗﻮﻳ ﺔ ﺑﻤﺎ ﻳﻜﻔـﻲ ﻨـﻊ اﻧﺘﺸﺎر اﻟﺒﻼزﻣﺎ ﺑـﻞ وﺣـ ـ ﴫﻫﺎ ﰲ اﻟﺨﻴـﻮط ا ﺮﻛﺰة اﻟﺘﻲ ﺗﻈﻬﺮ ﰲ ﺻﻮرة ﺗﻠﺴـﻜﻮب وﻳـﺐ ﻗﺪ ﺗﻘﺎوم ﻫﺬه ا ﺠﺎﻻت ا ﻐﻨﺎﻃﻴﺴﻴﺔ اﻟﻘﻮﻳـﺔ أﻳﻀ ﺎً اﻟﺠﺎذﺑﻴﺔ اﻟﺘﻲ ﻋﺎدةً ﻣﺎ ﺗﺘﺴﺒﺐ ﰲ اﻧﻬﻴﺎر ﺳﺤﺐ ﻛﺜﻴﻔﺔ ﻣـﻦ اﻟﻐـﺎز واﻟﻐﺒـﺎر وﺗﻜـﻮﻳﻦ اﻟﻨﺠﻮم ـ ﻣﻤﺎ ﻳﻔ ﴪ ﻣﻌـﺪل ﺗﻜـﻮﻳﻦ اﻟﻨﺠـﻮم اﻷﺑﻄﺄ ﻣﻦ ا ﺘﻮﻗﻊ ﰲ ﻣﻨﻄﻘﺔ ﺳﺎﺟﻴﺘﺎرﻳﻮس C ـــــــــــــــــــــــــــــــــــــ ﻗﺎل ﻛﺮو : " ﻫ ﺬا ﻣﺠـﺎل ﻣﺜـ ﻟﻠﺒﺤﺚ ا ﺴﺘﻘﺒﲇ ﺣﻴﺚ ﻟﻢ ﻳـﺘﻢ اﻟﻨﻈﺮ ﺑﺸـ ﻜﻞ ﻛﺎﻣـﻞ ﰲ ﺗـﺄﺛ ا ﺠﺎﻻت ا ﻐﻨ ﻄﻴﺴﻴﺔ اﻟﻘﻮﻳﺔ ﰲ ﻣ ﺮﻛــﺰ ا ﺠــﺮة أو ا ﺠــﺮات اﻷﺧﺮى ﻋﲆ اﻟﺒﻴﺌﺔ اﻟﻨﺠﻤﻴﺔ . إن ﻓﻬﻢ ﻛﻴﻔﻴـﺔ ﺗﺸـﻜﻴﻞ وﻻدة اﻟﻨﺠﻮم وﺗﻄﻮرﻫﺎ وﺣﺘﻰ ﻣﺼ اﻷ ﻧﻈﻤﺔ اﻟﻜﻮﻛﺒﻴـﺔ أﻣـﺮ ﺑـﺎﻟﻎ اﻷﻫﻤﻴﺔ ﻗﺪ ﺗﺆﺛﺮ ﻫـ ﺬه اﻟﻘـﻮى ﻋﲆ ﻛﻞ ﳾء ﺑﺪء ا ﻣﻦ ﺗﻜـﻮﻳﻦ اﻟﻨﺠ ــﻮم اﻟﺜﻨﺎﺋﻴ ــﺔ وﺣﺘ ــﻰ اﺳـﺘﻘﺮار اﻟﺴـﺤﺐ اﻟﺠﺰﻳﺌﻴ ـﺔ اﻟﺘﻲ ﺗﻨﻬﺎر ﻟﺘﻜﻮﻳﻦ اﻟﻨﺠﻮم . إن ﻫﺬه ا ﻌﺮﻓﺔ اﻟﺠﺪﻳﺪة ﺗﻌﺪﻧﺎ ﺑﺎﻛﺘﺸﺎﻓﺎت ﺛﻮرﻳﺔ ". ﻳﻮﻟﻴﻮ -
