BIGGEST TELESCOPE FROM NASA

BIGGEST TELESCOPE FROM NASA

American space agency NASA has made largest telescope of the WORLD till now successfully.

This gold mirror containing "JAMES WEB SPACE TELESCOPE"(JWST) will research on the secrets of the BIRTH OF UNIVERSE.

 It can find out the galaxies which were found after     BIG-BANG  and 13.5 billion  years ago from now.

It is HUNDRED TIMES more powerful than the HUBBLE telescope.




This is the HUBBLE telescope which was launched  in 1990 and working continuously from then.
Now JWST will be  kept at the place of HUBBLE telescope.
NASA engineers were working from 20 years on this telescope.





JAMES WEB SPACE TELESCOPE contains a 18 carat   GOLD PLATED MIRROR   of diameter 21 ft.


"THERE ARE INFRARED CAMERAS OF FIVE LAYERED SUN SHIELD."  






These sun shield layers are as thin as HUMAN HAIRS.



CAMERAS are so much sensitive that  it is very essential to protect them from sun light .










It's cost is 8 Billion Dollar  and it is as broad as tennis court  and approximately 32 FT. high









नासा की  सबसे बड़ी टेलीस्कोप
अमेरिकी अंतरिक्ष एजेंसी नासा ने दुनिया के अब तक के सबसे बड़े टेलीस्कोप को सफलतापूर्वक बना लिया  है।

"JAMES WEB SPACE TELESCOPE" (JWST) नामक  यह सोने का दर्पण युक्त  दूरबीन , ब्रह्मांण्ड  के जन्म के रहस्यों पर शोध करेगा।





 यह उन आकाशगंगाओं का पता लगा सकता है जो BIG-BANG के बाद मिली थीं और अब से 13.5 बिलियन साल पहले जन्मीं  थी ।

यह हबल टेलिस्कोप की तुलना में  सौ  गुना  अधिक शक्तिशाली है।





यह ह्यूबल टेलिस्कोप है जिसे 1990 में लॉन्च किया गया था और तब से लगातार काम कर रहा है।
 लगभग  २७ सालों  से  लगातार। 


 अब JWST को HUBBLE दूरबीन के स्थान पर रखा जाएगा।

 नासा के इंजीनियर इस टेलीस्कोप पर 20 साल से काम कर रहे थे।




 जेम्स वेब स्पेस टेलीस्कोप में 21 फीट व्यास का तथा  18 कैरेट  गोल्ड प्लेटेड मिरर है।

ये  परतें  मानव  के बाल  जितनी पतली हैं।






इसमें  लगे  कैमरे  इतने संवेदनशील हैं कि उन्हें सूरज की  शक्तिशाली किरणों  से बचाना बहुत आवश्यक है।


इसकी लागत 8 बिलियन डॉलर है और यह टेनिस कोर्ट  के  मैदान  जितना  चौड़ा और लगभग 32 फुट  ऊंचा  है।
अर्थात  तीन  मंजिला  ईमारत  जितनी  ऊंची।

Watan ke liye

                                                                watan ke liye vafadar bano.Chahe aap kisi dharm ya samu day ke ho,is baat se fark nahi padta.kyoki aap kisi bhi dharm ke ho,apke dharm ke ya samuday ke log kisi bhi desh me ho sakte hai.Do desh ek dusre ke dushman ya dost ho sakte hai,isliye aapka apne desh ke prati vafadar hona kafi aham ho jata hai. kyonki jo vyakti  jis bhi desh ki pahchan ke sath ji raha hai,use us desh ke prati imandar hona chahiye. wah desh apko apni nagrikta deta hai, apko sari pahchan deta hai us desh ke liye apko apki jimmedari to nibhani chahiye. #APNE DESH KE LIYE TO EK SALUTE BANTA HAI#

Surface Tension (you know???)

Surface Tension (you know???) water drops on glass surface when  a drop of water is placed on the surface of cleaned glass,then the water spread as a thin film on  glass surface. But when a drop of mercury is placed then it forms a small SPHERE. Similarly if there is greece on  glass surface then water drop will also form a tiny sphere.WHY????? mercury drop on glass surface Now the conclusion comes out that "the behavior of liquids is not affected only by the GRAVITATIONAL FORCE but there is another factor called surface tension. If a drop is of negligible weight then it has perfect spherical shape. For examples: rain drops, soap bubbles, etc. We should know that---------                                   "For a given volume a sphere has minimum surface area" Hence, it is the tendency of free surface to shrink to it's minimum surface area. How to define the ...

water vs temperature

Water  vs  Temperature Hello, friends here i'm going to tell you, how the behavior of water changes with respect to temperature .            We have seen that every liquid expand in volume on heating  but there is another situation in case of water  because water has HYDROGEN BONDING  and have DIPOLE MOMENT. now,in the case of water, when water is heated from 0 to 4 degree Celsius it's  volume decreases  and after 4 degree Celsius it's volume start to increase.             Due to this phenomenon, in our every day life we can see the natural secrets.  Now using this phenomenon ,                                              i'm going to tell you a number of natural effects. Density of water                 ...
