Kya Kabhi Socha Aapne?
Raat ko aasman mein sabse zyada roshan cheez jo nazar aati hai woh koi taara nahi woh Venus hai. Itna roshan ke log aksar ise shooting star samajh lete hain. Lekin yeh planet kahan se aaya? Kaise bana? Aur kyun yeh itna alag hai baaki planets se?
Aaj hum Venus ki poori kahani bilkul simple andaz mein samjhenge!
Venus Kya Hai?
Venus hamara solar system ka doosra planet hai suraj se doosre number par. Yeh Zameen ka sabse qareeb neighbor bhi hai aur size mein bhi Zameen ke kaafi qareeb hai isliye Venus ko aksar Zameen ka jora bhi kehte hain.
Lekin appearances dhokha de sakti hain Venus Zameen se bilkul alag hai. Yeh solar system ka sabse garam planet haiMercury nahi jo suraj ke zyada qareeb hai. Venus ki surface ka temperature 465 degree Celsius tak pohonchta hai itna garam ke seesa bhi pighal jaaye!
Venus Kaise Bana Shuruwaat
Venus ki kahani wahi se shuru hoti hai jahan se hamare poore solar system ki kahani shuru hoti hai aaj se roughly 4.6 billion saal pehle.
Jab solar nebula yaani gas aur dust ka bohat bada badal gravity ki wajah se sikunhna shuru hua aur suraj bana toh baaki gas aur dust suraj ke gird ek flat disk ki shakal mein ghoomne lagi. Is disk mein chhote chhote particles ek doosre se takraate aur chipakne lagte the.
Suraj se doosre number par jo material tha wahan temperature zyada tha lekin Mercury ke comparison mein thanda bhi tha. Is jagah par rocky materials ikatha hone lage chhote particles bade hote gaye bade aur bade aur phir ek waqt aaya jab yeh sab material ikatha hoke ek bade rocky planet ki shakal mein aa gaya. Yeh planet Venus tha.
Yeh poora process roughly 50 million saal mein poora hua kaainaat ke hisaab se yeh bohat jald hai!
Venus Aur Zameen Ek Jaisi Shuruwaat
Venus aur Zameen ne roughly ek hi waqt mein janam liya ek hi protoplanetary disk se roughly ek hi size ke saath. Dono rocky planets hain، dono ka mass roughly ek jaisa hai، dono ka size bhi kaafi milta julta hai.
Shuruwaat mein scientists ka khayal hai ke Venus aur Zameen kaafi milte julte the. Dono par shayad oceans the paani tha atmosphere tha. Lekin phir kuch hua jis ne Venus ko ek bilkul alag raah par daal diya.
Scientists abhi bhi poori tarah nahi jaante ke Venus itna alag kyun ho gaya lekin kuch theories zaroor hain jo is sawaal ka jawab dene ki koshish karti hain.
Venus Ka Atmosphere Ek Maut Ka Kambal
Venus ka atmosphere Zameen ke atmosphere se bilkul alag hai aur yahi Venus ki sabse badi khasiyat aur sabse bada masla bhi hai.
Venus ka atmosphere roughly 96 percent carbon dioxide se bana hai baaki nitrogen aur doosri gases hain. Yeh itna thick atmosphere hai ke Venus ki surface par pressure Zameen ki surface se 90 guna zyada hai bilkul aise jaise aap Zameen par 900 meter paani ke neeche hon.
Yeh thick carbon dioxide atmosphere ek greenhouse effect paida karta hai suraj ki garmi Venus mein daakhil hoti hai lekin bahar nahi nikal pati. Yahi wajah hai ke Venus itna garam hai Mercury se bhi zyada garam jabke Mercury suraj ke kaafi zyada qareeb hai.
Venus ke atmosphere mein sulfuric acid ke badal bhi hain yeh zehreela acid rain Venus par barasta rehta hai lekin itna garam hai ke surface tak pohonchne se pehle hi vapors ban jaata hai. Yeh manzar kitna khatarnak hoga!
Venus Ka Paani Kahan Gaya
Shuruwaat mein scientists ka khayal hai ke Venus par paani tha shayad oceans bhi the. Lekin yeh paani kahan gaya?
Venus suraj ke kaafi qareeb hai isliye suraj ki radiation bohat tezh thi. Yeh tezh radiation ne Venus ke paani ko tod kar hydrogen aur oxygen mein alag kar diya. Halki hydrogen gas aasman mein chali gayi aur oxygen rocky materials se jud gayi.
Jab paani khatam hua toh Venus ki surface par koi plate tectonics nahi rahi yeh woh process hai jo Zameen par rocks ko recycle karta rehta hai aur carbon dioxide ko atmosphere se bahar rakhta hai. Venus par yeh process ruk gayi toh carbon dioxide atmosphere mein ikathi hoti gayi aur greenhouse effect bohat zyada ho gaya.
Yahi wajah hai ke Venus aaj itna garam aur zehreela planet hai ek aisi jagah jahan zindagi ka koi imkan nahi.
Venus Ka Ulta Ghoomna Ek Dilchasp Raaz
Venus ki ek aur bohat hairat angez baat hai yeh ulti direction mein ghoomta hai baaki zyada tar planets ke muqabley mein.
Hamare solar system ke zyada tar planets ek hi direction mein ghoomte hain lekin Venus ulti taraf ghoomta hai. Agar aap Venus par khade ho kar suraj dekhen toh suraj west se ughta aur east mein dubta nazar aayega bilkul Zameen ke ulta.
Aur Venus itna dheere ghoomta hai ke Venus par ek din yaani Venus ka ek chakkar apni axis parZameen ke din ke barabar hai. Lekin Venus ka ek saal yaani suraj ka ek chakkar sirf 225 Zameen ke din ka hota hai. Matlab Venus par din saal se lamba hota hai kitni ajeeb baat hai!
Scientists abhi bhi poori tarah nahi jaante ke Venus ulta kyun ghoomta hai. Ek theory yeh hai ke shuruwaat mein kisi bari cheez se takkar aayi jis ne Venus ka rotation ulta kar diya. Doosri theory yeh hai ke Venus ki thick atmosphere ki wajah se yeh dheere dheere ulta ho gaya.
Venus Ki Surface Andar Kya Hai
Venus ki surface bohat mushkil jagah hai lekin scientists ne space probes bhej kar kaafi kuch jaana hai. Soviet Union ne 1970 aur 1980 ke dasaion mein kai probes Venus par utare the yeh ek bohat bari kamyabi thi lekin extreme temperature aur pressure ki wajah se yeh probes sirf kuch ghante hi zinda reh paye.
Venus ki surface par bohat saare volcanoes hain scientists ka khayal hai ke kuch abhi bhi active hain. Haal hi mein NASA ke data se pata chala ke Venus par ab bhi volcanic activity ho rahi hai matlab Venus abhi bhi geologically zinda hai.
Venus ki surface par vast plains، highland regions aur deep valleys bhi hain. Sabse bada highland region Aphrodite Terra hai jo Africa ke size ka hai. Sabse unchi jagah Maxwell Montes hai jo Zameen ke Mount Everest se bhi unchi hai.
Venus par impact craters bhi hain lekin Zameen aur Chaand ke muqabley mein kam hain. Iska matlab yeh hai ke Venus ki surface kaafi nai hai volcanic activity ne purani surface ko daba diya aur nai surface bana di.
Venus Ko Explore Karna Kitna Mushkil
Venus ko explore karna solar system mein sabse mushkil kamon mein se ek hai. 465 degree Celsius temperature aur 90 guna zyada pressure mein koi bhi spacecraft zyada der nahi chal sakta.
Soviet Union ke Venera probes sabse zyada der tak Venus par rahe lekin woh bhi sirf 2 se 3 ghante hi zinda reh paye aur phir extreme conditions ne unhe band kar diya.
NASA aur European Space Agency ne Venus ke gird orbit mein spacecraft bheje hain jinhon ne radar se Venus ki surface ka naksha banaya aur atmosphere ka study kiya. Lekin surface par jaana abhi bhi bohat mushkil hai.
Future mein NASA ka DAVINCI aur VERITAS mission Venus ko aur gehrai se explore karne ka plan hai. Scientists ummeed kar rahe hain ke in missions se Venus ke raaz aur zyada khulenge.
Venus Aur Zindagi Kya Mumkin Hai
Venus ki surface par zindagi ka koi imkan nahi bohat zyada garam، bohat zyada pressure، aur zehreela atmosphere.
Lekin ek dilchasp theory hai Venus ke upper atmosphere mein jahan temperature aur pressure Zameen ke surface jaise hain kya wahan koi simple life form ho sakta hai?
2020 mein ek study mein Venus ke atmosphere mein phosphine gas dekhne ka dawa kiya gaya yeh ek aisi gas hai jo Zameen par sirf living organisms banate hain. Yeh ek bohat bada claim tha aur scientists abhi bhi is par debate kar rahe hain kuch kehte hain yeh measurement galat thi، kuch kehte hain aur study chahiye.
Lekin yeh bhi sach hai ke Venus ka upper atmosphere ek aisi jagah hai jahan conditions utni buri nahi aur science mein kabhi bhi impossible kehna theek nahi hota!
Aakhri Baat Zameen Ka Aaeena
Venus ko dekhna ek tarah se Zameen ka aaeena dekhna hai ek aisi duniya jo hamari Zameen jaisi shuru hui lekin bilkul alag ho gayi.
Yeh hamein yaad dilata hai ke kitni nazuk conditions mein zindagi pali hai Zameen par paani، sahi temperature، sahi atmosphere yeh sab ittifaq nahi tha balke ek bohat lambi aur nazuk kahani ka nateeja hai.
Agli baar jab raat ko roshan Venus aasman mein dekhen yaad karain ke woh khubsoorat roshan cheez asal mein ek bohat khatarnak aur ajeeb duniya hai jo hamari apni Zameen ki ek chetavni bhi hai ke agar hum apni atmosphere ka khayal na rakhein toh hum bhi Venus ban sakte hain!
