Naye Pani Wale Siyaray 2025: K2-18 b, GJ 9827 d aur HD 149026 b ki Daryaft
Table of Contents
Taaruf
Space missions aur jadeed dor ke telescopes ki madad se hum ab apne solar system ke bahar hazaron sayaroun ki daryaft kar chuke hain. In mein se chand sayaroun mein paani ke mojood hone ke saboot mile hain, jo zindagi ki talaash ke hawale se intehai ahamiyat rakhte hain. Hal hi mein NASA aur doosre scientific idaron ne aise naye sayaroun ka ailan kiya hai jinki fiza ya satah par paani ke asar paye gaye hain.
Is report mein hum teen aham misaalon par roshni dalenge:
- Super-Earth siyarah K2-18 b
- Sub-Neptune type siyarah GJ 9827 d
- Garam gas giant HD 149026 b (Smertrios)
Har siyarah ka naam, uske charo taraf ka sitara, paani ke saboot, fiza aur jismi khususiyaat, aur zindagi ke imkanat ka tajziya pesh kiya jayega.
Siyarah K2-18 b
K2-18 b ek Super-Earth type siyarah hai jo NASA ke James Webb Space Telescope (JWST) se jadeed mutaliat ke zariye mashhoor hui. Ye siyarah apne surkh dwarf sitare K2-18 ke gird takriban 33 zameeni dino mein gardish karta hai aur Leo constellation mein zameen se 120 light years door hai.
Paani ke Saboot:
JWST ne K2-18 b ki atmospheric spectrum mein methane aur carbon dioxide ki mojoodgi ko tasdeeq kiya. Inki miqdaar se andaza hota hai ke is siyarah ki fiza hydrogen se bharpoor hai aur iske andar ya satah par paani ka samundar ho sakta hai. Research ke mutabiq, K2-18 b ek “Hycean” siyarah ho sakta hai – yani hydrogen se bhara hua aur paani se covered siyarah. Space.com ke mutabiq, “Siyarah K2-18 b muaqi pani se itna bharpoor hai ke ye samundar wala siyarah sabit ho sakta hai.”
Jismi Khususiyaat:
- Wazan: Zameen ka 8.6 guna
- Radius: Zameen ka takriban 2 guna
- Sitara: Cool dwarf, is liye siyarah relatively thanda
- Temperature: Pani ko liquid state mein rakhne ke laayak
Zindagi ke Imkanat:
Pani ki mojoodgi aur mouafiq darja hararat ki wajah se ye siyarah zindagi ke liye aham mana jata hai. Cambridge University ke expert ke mutabiq, “Ye tasdeeq karta hai ke K2-18 b hamari solar system ke bahar zindagi ke mutalaay ke liye behtareen mauqa hai.”
Siyarah GJ 9827 d
GJ 9827 d zameen se takriban 97 light years door ek surkh dwarf sitare GJ 9827 ke gird gardish karta hai. Iska diameter zameen se lagbhag do guna aur wazan zameen ka 3 guna hai.
Paani ke Saboot:
NASA ke Hubble Space Telescope ne GJ 9827 d ki fiza mein paani ke vapors ka pata lagaya. NASA ke mutabiq ye “sab se chhota siyarah hai jiske atmosphere mein paani ke vapors dekhe gaye.” James Webb Telescope ke naye observations ne bhi is siyarah ki fiza mein paani ke molecules ki tasdeeq ki.
Jismi Khususiyaat:
- Temperature: Din ke pehlu par 340°C, yaani bohot garam
- Paani ka zyada hissa vapors mein hai
- Kuch theories ke mutabiq, siyarah ka asal orbit door tha aur baad mein star ke kareeb aaya, jahan hydrogen ka zyada hissa chala gaya
Zindagi ke Imkanat:
Bohot zyada garam hone aur paani ke vapors mein hone ki wajah se zindagi ke imkanat kam hain. Atmosphere ka pressure bohot zyada hai, jo pani ko supercritical ya high-pressure ice jaise states mein convert kar sakta hai.
Siyarah HD 149026 b (Smertrios)
HD 149026 b, jise Smertrios bhi kehte hain, ek garam gas giant hai jo yellow sub-dwarf sitare HD 149026 ke kareeb orbit karta hai. Ye zameen se takriban 247 light years door hai aur iska orbit sirf chand dino mein complete hota hai.
Paani ke Saboot:
German CARMENES telescope ke zariye 2023 mein iski fiza ka analysis hua aur paani ke molecules ke vapors ka pata chala. Ye paani ki mojoodgi ka pehla saboot hai.
Jismi Khususiyaat:
- Size: Jupiter ka 75%
- Temperature: Din ke pehlu par 2600°F tak
- High metal content, strong gravity
Zindagi ke Imkanat:
Bohot zyada garam aur extreme atmosphere ki wajah se zindagi ke imkanat bohot kam hain.
Zindagi ke Imkanat ka Tajziya
- K2-18 b: Pani aur moderate temperature ke saath zindagi ke liye sab se mumkin siyarah
- GJ 9827 d & HD 149026 b: Boht zyada garam, pani vapors mein, zindagi ke liye na-mumkin
Ye saboot dikhate hain ke sirf pani ka hona hi zindagi ke liye kaafi nahi, temperature, pressure aur chemical environment bhi zaroori hai.
Nateeja aur Tajziya
Jadeed telescopes (JWST, Hubble) ke zariye hum ab un sayaroun ka tajziya kar sakte hain jahan pani ke molecules ya vapors mojood hain. NASA ki daryaft ne sabit kiya ke humari galaxy mein pani wale aur mukhtalif type ke sayarah paye jaate hain. K2-18 b aur GJ 9827 d jaise examples hume pani wale unknown environments ka tajziya karne ka mauqa dete hain. Future telescopes in sayaroun mein oxygen aur other biosignature gases detect kar sakenge, jisse ye maloom hoga ke wahan zindagi ka koi mumkin imkaan hai ya nahi.
