The James Webb Space Telescope is the world’s largest man-made, most powerful, and most nexus science telescope ever built-in human history. The telescope will solve trillions of mysteries in our solar system, look beyond to distant worlds around other stars, galaxies and other heavenly bodies of our universe, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA (National Aeronautics and Space Administration), collaborating with its partners, ESA (European Space Agency) and the Canadian Space Agency.
James Webb Telescope will be able to observe the planets at or beyond the orbit of Mars, satellites, comets, asteroids, and Kuiper belt objects. Many important molecules, ices, minerals and bodies have strong characteristics signatures and symbols at the wavelengths Webb can observe. Webb will also monitor the weather of planets and their natural satellites with the deep look on its atmosphere too.
After the lunch of telescope in 25th of December, 2021 on a mission to study the earliest stars and peer back farther into the universe’s past than ever before, well infact before the birth of our home planet ‘Earth’. Webb is currently at its observing spot, Lagrange Point 2(L), nearly 1 million miles (1.6 million km) from the Earth. In addition, Webb is the largest and most powerful space telescope ever launched.
Is James Webb telescope more powerful and worthy than The Hubble telescope?
Well, James Webb Telescope is much more powerful comparatively to Hubble. The Webb is the successor to Hubble, and on a serious note Webb is 100 times more powerful. Webb also has a much bigger mirror than Hubble, explains the Webb telescope site: “This larger light-collecting area means that Webb can peer farther back into time than Hubble is capable of doing.”
Similarly, the Webb is primarily an infrared telescope, so it sees light that’s in a longer wavelength than what our eyes can see. This seems nerdy and technical, but it’s actually what allows Webb to look further back in time than the Hubble. Infrared light is often very old light, due to a phenomenon call redshirting.
After separating from its launch vehicle, JWST began to slow rapidly and it is now travelling at a cruising speed of around 0.2 miles per second towards L2, or roughly 720 miles per hour. Moreover the $10 Billion price sounds inordinately high – and – it is – the JSWT is the world’s largest and most powerful science telescope in space. It is expected to help researchers unearth everything from mysteries of the Big Bang to alien planet formation.
In conclusion, not just the next space telescope to be launched – likely NASA’s new project named Nancy Grace Roman telescope which is projected to be launched by 2027 – but the next Webb-like telescope: a big flagship project for the future, recommended by astronomers today.
