  James Webb Space Telescope IMAGE CREDIT: NASA INTRODUCTION: James Webb Space Telescope is also Known as JWST, JAMES WEBB is a space telescope jointly developed by NASA, ESA, CSA & STSI. History of JAMES WEBB: After the launch of the Hubble space telescope(HST), engineers thought of building a more powerful space telescope than Hubble. This new idea started in 1996. Then, after a lot of funding issues, the construction of James Webb began. Companies participating in James Webb mission : NASA, ESA(European Space Agency), CSA(Canadian Space agency) & STSI (Space telescope Science Institute) are the companies   responsible for James Webb . STSI gave the IDEA of JWST. THIS COMPANY HELPS TO OPERATE HST also . LOCATION OF JWST: image credit: NASA Unlike HST, JWST will be located in the LAGRANGE point 2 of earth. L2 is a point where a spacecraft doesn't need more fuel to stay at the same point. To know more about it, you can visit my previous blogs. Scientists chose L2 as Li...
