PARIS (The Thursday Times) — Europi khalai agency ki Euclid khalai doorbeen ne apne data ka pehla bara hissa jari kar diya hai, jis mein 90 crore se zaid kehkashaon ka indiraj hai. Is ke sath woh kainat ke ab tak ke sab se bare seh-jihati naqshe par kaam shuru kar rahi hai.
Agency ke mutabiq DR1-Foundation naami yeh ijra Jumeraat ko aam kiya gaya aur taqriban 13 mah ke mushahidat par mabni hai. Yeh aasman ke 1,900 murabba darje par muheet hai, yani taqriban saarhe nau hazar poore chandon jitna raqba, aur is ka hajm 17 lakh gigabyte hai.
Kehkashaon ke sath is mein chhe crore se zaid mumkina quasar bhi shamil hain, yani door daraz kehkashaon ke woh roshan markaz jinhein bohat bare black hole tawanai dete hain. Is ke ilawa 16 crore se zaid ajsam ke spectra aur mazboot gravitational lensing ke taqriban 15 hazar ummeedwar bhi hain.
Agency ki director science Carole Mundell ne kaha: “Yeh mehz khoobsurat tasaveer se kahin barh kar hain; aaj ka din kainat ke mutale mein ek scienci sang-e-meel hai.” Euclid ki project scientist Valeria Pettorino ne ise pichhle ijra ke muqable mein “paimane ki tabdeeli” qarar diya, jo chand dinon ke mushahidat aur taqriban 60 murabba darje par mushtamil the.
Tareek kainat ki talash
Euclid July 2023 mein tareek tawanai aur tareek madde ke mutale ke liye bheji gayi thi, jin ke bare mein khayal hai ke yeh mil kar kainat ka taqriban 95 fisad hain lekin barah-e-rast dikhai nahin dete. Is ka chhe sala survey arbon kehkashaon ki shaklen aur croron ke faasle naape ga.
Mazboot gravitational lensing, jis mein samne ki koi kehkashan door ki kehkashan ki roshni ko mor kar qaus ya halqe ki shakal de deti hai, is ka sab se tez hathiyar hai. Chunke yeh asar qareebi kehkashan ki kamiyat par munhasir hai, jis mein tareek madda bhi shamil hai, is liye scientist un kehkashaon ka wazan naap sakte hain jo poori tarah dikhai nahin detin.
University of Edinburgh ke Andy Taylor, jo mission ke Bartanvi science ground segment ki qiyadat karte hain, ke mutabiq Euclid se pehle scientist aise taqriban ek hazar lens jante the. Nayi fehrist mein taqriban 15 hazar mumkina case hain, aur mission ke ikhtitam tak taqriban ek lakh 70 hazar mutawaqqa hain.
Yeh to sirf aaghaz hai
Yeh ijra us aasman ke sirf taqriban 14 fisad hisse par mushtamil hai jis ka Euclid aakhirkar naqsha banaye gi. Mukammal pehla data ijra 2027 ke wast mein mutawaqqa hai, jis mein weak lensing, yani woh maddham bigaar jin ki madad se scientist kainat mein tareek madde ki jagah ka naqsha banayenge, aur kehkashaon aur jhurmuton ke kainati jaal mein maqam ka data shamil hoga.
Euclid Europi khalai agency ne banayi hai aur wohi ise chalati hai, jabke NASA ne bhi is mein hissa dala hai. Euclid Consortium, jo is ke aalaat faraham karta aur data ka tajziya karta hai, Europe, America, Canada, aur Japan ke 300 idaron ke do hazar se zaid scientists par mushtamil hai.
