JAMES WEB SPACE TELESCOPE

The desire to know what is going on in the sky dates back to the time of man. So they realized the need for telescopes long ago.

Its first structure was designed in 1608 by Hans Lippershey, a spectacle maker. Inspiration from it led to the creation of the Galileo Telescope.
As science grew, man’s zeal to discover the depths of the universe led him to build a more powerful telescope.
It was forced to be placed in space when viewing from Earth caused many shortcomings.
Space telescopes can give us more accurate view of the universe than terrestrial telescopes.

When light from distant objects passes through the Earth’s atmosphere, that light is subjected to various types of dimming. In addition, clouds and dust often interfere with Earth’s celestial observations. A telescope placed in space does not have a telescope similar to the one placed on Earth to lie accurately and in angular resolution.

Because of these facts, the Hubble Space Telescope, launched into orbit in the early nineties, became a milestone in astronomical history. Despite having much larger telescopes than the Hubble Space Telescope on Earth’s surface, Hubble was able to take the most accurate images of distant objects in the universe.

For the past quarter century, the Hubble Space Telescope has been continuously providing images of distant objects in the universe. The Hubble Space Telescope is no longer very accurate due to obsolescence and the failure of the U.S. space shuttles.

It was in this context that NASA and the European Space Agency teamed up to build another more capable space telescope.
(James Edwin Webb (1906 – 1992) was a former senior NASA official.

The James Web Space Telescope is much larger than the Hubble Space Telescope. The diameter of the Hubble primary reflector mirror is 2.4 meters, while that of the Hubble Space Telescope is 6.5 meters. Therefore, the James Web Space Telescope could be four times the light of the Hubble Space Telescope. The Hubble Space Telescope orbited the Earth in a low orbit.

The James Web Space Telescope will be able to observe space at an infrared frequency higher than the Hubble.
Even so, the James Web Space Telescope weighs only half the weight of the 11,000 kg Hubble Space Telescope.
Construction of the James Web Space Telescope began in the 1990s.
The project was once almost abandoned due to heavy costs. Yet despite the constant cost increases, the James Web Space Telescope is nearing completion.
All the important parts of the telescope have been built. The final test of the machine parts is underway .In the 1990s, the launch of the James Web Space Telescope was expected to take place in 2007. The launch of the James Webb Space Telescope, which has been delayed several times due to technical and financial reasons, is expected to take place in 2021 in French Guiana using the Ariane-5 launch vehicle.
When activated, the James Web Space Telescope will show us aerial views that we have never seen before .The James Web Space Telescope is expected to provide images that are ten times more accurate than the Hubble Space Telescope.
