JANUARY-FEBRUARY2026 about the nature of the accretion process.Remarkably,magneticac- tivity appears to have played arole in driving the dramatic infall of mass, something that has only been observed in stars before.This suggests that even low-mass objects can possess strong mag- netic fields capable of powering such accretion events. The team also found that the chemistry of the disc around the planetchangedduringtheaccre- tion episode, with water vapour being detected during it but not before. This phenomenon had beenspottedinstarsbutneverin aplanetofanykind.Free-floating planetsaredifficulttodetect,as theyareveryfaint,butESO’sup- coming Extremely Large Telescope (ELT),operatingundertheworld's darkestskiesforastronomy,could change that. Its powerful instru- ments and giant main mirror will enable astronomers to uncover and study more of these lonely planets, helping them to better understand how star-like they are. Asco-authorandESOastronomer Amelia Bayo puts it: “The idea that a planetary object can be- have like a star is awe-inspiring and invites us to wonder what worlds beyond our own could be likeduringtheirnascentstages.”   ﺗﻈﻬــــــــﺮ ﻫــــــــﺬﻩ اﻟﺼــــــــﻮرة ﺎﻷﺷــــــــﻌﺔ ﺗﺤـــــــــﺖ ـاﻟ ﻤﺮاء اﻟﻤﻠﺘﻘﻄـﺔ ﺑﻮاﺳـﻄﺔ ﺗﻠﺴـ ﻮب ا ﻟﺮﺻـﺪ ــــــــﺔ اﻟﻤﺮــــــــﻲوﺗﺤــــــــﺖ اﻷ ﻤــــــــﺮﻟﻸﺑﺤــــــــﺎث اﻟﻔﻠﻜ ) ( ﻓ ﺴــﺘﺎ اﻟﺘـــﺎﺑﻊ ﻟ ﻠﻤﺮﺻــﺪ اﻷوروﺑـــﻲ اﻟـــ ـ ﺠﻨﻮﺑﻲ ﻣﻮﻗـــــــﻊ اﻟ ﻮﻛــــــــﺐ اﻟﺸــــــــﺎرد 1107-7626 Cha ﻓـــــــــﻲ اﻟﺴـــــــــﻤﺎء و ﻈﻬـــــــــﺮاﻟ ﻮﻛـــــــــﺐ ﻛﻨﻘﻄـــــــــﺔ ﺻــﻐ ة ﺗﻘـــﻊ ﺗﻤﺎﻣـــ ﺎ ﻓـــﻲﻣﺮﻛـــﺰ إﻃـــﺎر اﻟﺼـــﻮرة [ESO/Meingast et al.] أﻣﺎ ﺻﻮرة اﻟﻤﻠﺘﻘﻄﺔ ﻓﻲ اﻟﻀﻮء اﻟﻤﺮﻲ ﻓﻲ اﻷﺳـــــــﻔﻞ وﻫـــــــﻲﺟـــــــﺰء ﻣـــــــﻦ ﻣﺴـــــــﺢ اﻟﺴـــــــﻤﺎء اﻟﺮﻗﻤﻲ اﻟﺜﺎﻧﻲ ﻓﺘﻈﻬﺮ أ ﻀـ ﺎً ﻣﻮﻗـﻊ اﻟ ﻮﻛـﺐ اﻟﺸــــــــــﺎرد 1107-7626 Cha ﻓــــــــــﻲ اﻟﺴـــــــــــﻤﺎء . اﻟ ﻮﻛـــﺐ ﻏـــ ﻣﺮـــﻲﻓـــﻲﻫـــﺬﻩ اﻟﺼـــﻮرة ﻟﻜﻨـــﮫ ﻘﻊ ﻫﻮ اﻵﺧﺮ ﺪﻗﺔ ﻓﻲﻣﺮﻛﺰ إﻃﺎراﻟﺼﻮرة .
