Suraj Kya Hai Aur Kaise Bana? Janiye Iska Pura Sach Aur Rahasya

Suraj Kya Hai Aur Ye Kaise Aaya?

Suraj hamare solar system ka sabse bada aur sabse mahatvapurna hissa hai. Agar aasan shabdon me kahein, to Suraj ek bohot hi vishal aur garm gas ka gola hai. Ye hamari dharti se lagbhag 150 million kilometer door hai. Iske bina hamare solar system ka koi vajood nahi hai. Lekin kya aapne kabhi socha hai ki ye Suraj aakhir aaya kahan se? Iska janam kaise hua?

Lagbhag 4.6 billion saal pehle, space me sirf dhool aur gasses ka ek bohot bada badal tha. Is badal ko scientists Giant Molecular Cloud ya Nebula kehte hain. Ek din is badal me gravity ki wajah se halchal hui. Gravity ne is pure badal ko andar ki taraf khinchana shuru kar diya. Jab ye badal collapse hone laga, to iske center me bohot zyada pressure aur garmi badhne lagi. Is tarah hamare pyare Suraj ka janam hua. Is puri prakriya ko samajhne ke liye aap niche diye gaye diagram ko dekh sakte hain.

Suraj Me Aag Jaisi Garmi Kyu Rehti Hai?

Bohot se logon ko lagta hai ki Suraj me koi lakdi, koyla ya petrol jal raha hai. Lekin aisa bilkul nahi hai. Space me oxygen nahi hoti, isliye wahan aam aag nahi jal sakti. Suraj ke andar ek alag hi tarah ki process hoti hai jise Nuclear Fusion (Nabhikiya Sanlayan) kehte hain. Suraj ka lagbhag 74% hissa Hydrogen gas se aur 24% hissa Helium gas se bana hai.

Suraj ke center (core) me gravity ka pressure itna zyada hota hai ki Hydrogen ke atoms aapas me takrate hain aur judkar Helium banate hain. Is process me bohot hi bhayanak matra me energy aur light nikalti hai. Yahi energy hume dhoop aur garmi ke roop me milti hai. Har second Suraj me lakho ton Hydrogen, Helium me badalti hai. Is nuclear reaction ki wajah se hi Suraj hamesha chamakta aur garm rehta hai.

Agar Suraj Na Ho To Kya Hoga?

Agar kisi din Suraj achanak gayab ho jaye, to hamari dharti par tabahi mach jayegi. Sabse pehle, Suraj ki roshni ko dharti tak pahunchne me 8 minute aur 20 second ka samay lagta hai. Isliye gayab hone ke thik 8 minute baad dharti par puri tarah andhera chha jayega. Chand bhi chamakna band kar dega kyunki wo bhi Suraj ki roshni se hi chamakta hai.

Iske baad jo hoga wo aur bhi bhayanak hai. Suraj ki gravity hi sabhi planets ko apni jagah par banaye rakhti hai. Gravity khatam hote hi dharti space me ek taraf behisab tairne lagegai. Ek hafte ke andar dharti ka temperature minus 17 degree Celsius tak gir jayega. Sabhi ped-paudhe bina dhoop ke photosynthesis nahi kar payenge aur mar jayenge. Kuch hi mahino me dharti ke saare samundar jam jayenge aur dharti ek baraf ka gola ban jayegi. In sabhi badlavo ko aap niche diye gaye diagram me dekh sakte hain.

Kya Hum Suraj Par Reh Sakte Hain?

Iska seedha aur aasan jawab hai - Bilkul Nahi! Suraj par jana ya wahan rehna kisi bhi tarah se mumkin nahi hai. Iske piche kai bade kaaran hain. Sabse pehla kaaran hai wahan ka behad garm temperature. Suraj ki satah (surface) ka temperature lagbhag 5,500 degree Celsius hota hai. Iske center ka temperature to 15 million degree Celsius tak pahunch jata hai. Itne temperature me koi bhi cheez palak jhapakte hi bhaap ban jayegi.

Dusra bada kaaran ye hai ki Suraj ke paas dharti ki tarah koi thos zameen (solid surface) nahi hai. Wo sirf garm gasses aur plasma se bana hai. Agar aap wahan jayenge bhi, to khade hone ke liye koi jagah nahi milegi. Iske alawa, Suraj ka radiation aur gravity itni zyada hai ki koi bhi spacecraft uske paas pahunchne se pehle hi jal kar rakh ho jayega. NASA ne apna Parker Solar Probe bheja hai, jo dur se hi iska adhyayan kar raha hai.

Suraj Aur Earth Me Itna Antar Kyu Hai?

Dharti aur Suraj me zameen-aasman ka antar hai. Dharti ek rocky planet (pathreela grah) hai, jabki Suraj ek star (tara) hai. Dharti par pani, hawa aur ek thos satah hai jo jeevan ko sambhav banati hai. Wahan ka temperature na to bohot zyada garm hai aur na hi bohot zyada thanda. Iske viprit, Suraj par sirf hydrogen aur helium gas ka dabdaba hai.

Suraj ka size dharti se lagbhag 1.3 million guna bada hai. Iska matlab hai ki Suraj ke andar 13 lakh dharti aasan se sama sakti hain. Suraj me itna bada badlav iske janam ke samay hi ho gaya tha jab usne solar system ki lagbhag 99.8% mass (drabyaman) apne andar samet liya tha. Niche diye gaye diagram me aap dono ki banavat ka antar dekh sakte hain.

Conclusion

Suraj hamare liye ek vardan hai. Iske bina dharti par na to koi ped-paudha hota aur na hi hum insaan hote. Suraj ki garm gas aur nuclear fusion hi hamare solar system ko chalaye rakhte hain. Halanki hum wahan kabhi ja nahi sakte, lekin uski roshni aur garmi hamare jeevan ka sabse bada aadhar hain.
