kia hamari kehkashan mai kherbon ” yateem sayaray” hain?
kia hamari kehkashan mai kherbon ” yateem sayaray” hain, aik taaza tahaqeeq mein mahireen falkiaat nay andaza lagaya hai ke hamari kehkashan mein’ yateem sayyaron’ ki tadaad sitaron se bhi ziyada, yani kayi kharab hosakti hai.’ yateem’ ya’ badmaash’ sayaray woh hotay hain jo kisi setaaray ke gird chakkar nahi laga rahay hotay balkay khala mein azadana aawara gardi kar rahay hotay hain .
ab taq ke mohtaat tareen andazon ke mutabiq, hamari mulki way kehkashan mein sitaron ki tadaad 100 arab ( aik kharab ) se le kar 400 arab ( chaar kharab ) taq hosakti hai .( jee haan! yeh sach hai ke hum abhi taq khud apni hi kehkashan ke barey mein poooray wusooq se yeh baat nahi jantay. )
” astronomical journal’ ‘ ke taaza shmare mein shaya honay wali tahaqeeq ke mutabiq,state university ke mahireen nay takhmeenah lagaya hai ke hamari apni’ ‘ mulki way’ ‘ kehkashan mein yateem sayyaron ki tadaad 400 arab se bhi ziyada hosakti hai .
yeh’ yateem sayaray’ kaisay bantay hain? is barey mein hamaray paas kuch mfrozat zaroor hain lekin koi saabit shuda scienci nazriya mojood nahi .
Amrici khalayi tehqeeqi idaray’ ‘ Nasa ‘ ‘ ki’ ‘ ninsi grace roman khalayi doorbeen’ ‘ jo 2025 taq khala mein bhejnay ka mansoobah hai, dosray sitaron ke gird sayaray dhoandne ke ilawa yateem sayyaron ki talaash bhi kere gi. is maqsad ke liye yeh –apne hassas alaat istemaal karte hue’ ‘ micro lensing ‘ ‘ Nami qudrati Mazhar se istifada kere gi .
mahireen ko umeed hai ke yeh doorbeen secron ki tadaad mein yateem sayaray daryaft karle gi, jis ke baad yateem sayyaron ki takhleeq ke barey mein mfrozat ki tasdeeq ya tardeed ki jasakay gi .
yateem sayyaron ke barey mein aik mafrooza to yeh hai ke aaj se karorron arbon saal pehlay yeh bhi sitaron ke gird baqaida gardish kar rahay they lekin phir, shayad –apne sitaron ke khatam hojane ya un ki qotِ saqal ( gravity ) bohat kamzor prhjane ki wajah se, yeh –apne mdaron se azad ho kar khalaa mein idher se udher aawara gardi karne lagey .
yeh aur un jaisi doosri baate fil haal mfrozon hi ki shakal mein hain jinhein qabil e bharosa mshahdat ki bunyaad par tasdeeq ya tardeed ki laazmi zaroorat hai. Nasa ki ninsi grace roman khalayi doorbeen ki tayari mein is zaroorat ko bhi btorِ khaas mad-e-nazar rakha gaya hai .
batatay chalen ke 1998 se le kar ab taq 20 yateem sayaray hi daryaft hue hain jabkay un mein se bhi sirf do sayaray aisay hain jinhein musadeqa tor par yateem sayaray tasleem kya gaya hai ؛ baqi 18 ka shumaar’ ‘ umeed waar yateem sayyaron’ ‘ mein kya jata hai jin ke barey mein fi al haal hatmi tor par kuch nahi kaha ja sakta .
