James Webb Space Telescope: Dimensions and Design
The most important part of a space telescope is the size of its mirrors that it has. The main and the primary mirror of the James webpage telescope consists of a total of 18 hexagonal mirror blocks which are gold plated by beryllium that forms a total of 21 feet mirror as compared to the 7 feet mirror in the previous generation Hubble space telescope.
The large primary mirror gives an advantage to the James Webb telescope to collect more light from distant stars and planets of about 25 square meters which is 6 times larger than the previous generation. The Hubble space telescope only worked by using ultraviolet and visible lights but in the James Webb telescope, we also have the wavelength of infrared lights.
The James Webb telescope is deployed at an L2 Lagrange point which is approximately 1.5 million kilometers from the earth where the gravitational point is the most stable in the entire space. It also protects that telescope from the extremely hot temperature of the sun.
James Webb Space Telescope | Largest Telescope in the World
Do you want to know which is the world’s largest space telescope and where it is situated? So, the answer is the James Webb Space Telescope. The James Webb space telescope is the world’s largest infrared astronomy telescope that has improved the infrared resolution of faraway objects as compared to the Hubble space telescope.
National Aeronautics and Space Administration (NASA) recently launched the space telescope on 25 December 2021. NASA released the first images obtained by the space Webb telescope on July 12th, 2022. This telescope cost 10 billion dollars to NASA to build and it is by far the most powerful telescope that can even see the entire galaxy.
The James Webb space telescope took 30 days to reach its destination point called L2 Lagrange point which is the most stable gravitational place in space. This is a place that is an equal distance from the earth and the sun and it cancels out the gravity between the Earth and the Sun so it is very stable. The James Webb space telescope was mainly built to see the light in the universe, the assembly of galaxies, the birth and death of the star and planets, and the presence of water on various planets.
