The cost is USD 10Billions !

Hope of 17 countries, James Webb telescope launch in December
The US space agency, NASA, has announced that the launch of the James Webb Telescope, the world’s most expensive telescope, will take place in December, as previously announced. Last year, the launch of the James Webb Space Telescope was postponed to October 31, 2021 due to workplace restrictions due to the corona virus epidemic.
Attempts were made to launch in March 2020 as well. Originally conceived in 1996, it was originally intended to launch in 2007. This expensive telescope will be used to be placed at a distance of one million miles (15 million kilometers) from the earth.

The James Web Space Telescope is NASA’s next generation technology. The James Web Space Telescope, like the Kepler, is capable of making great discoveries and discoveries in space. NASA researchers hope to make major discoveries once the telescope becomes operational.
Built of gold glass, the telescope will cost $ 10 billion to collect light from the universe and study facts such as the Big Bang, the origin of stars, and the formation of the first Milky Way. The telescope will also be able to detect black holes in the Milky Way, stars, planets and the origin of life.

The construction of the main mirror was completed in 2017. The James Web Space Telescope is better than the current Hubble Space Telescope and the Spitzer Space Telescope. Its main mirror is 6.5 meters in diameter.
In 1996, researchers began discussing the first such project. It is also a joint venture of 17 countries. NASA, the European Space Agency and the Canadian Space Agency are also part of it. James E., NASA’s second administrator. This telescope is named after the web.

The project was originally called the Next Generation Space Telescope.
The mirror made of gold by the James Web Space Telescope is capable of collecting five times as much information as the Hubble Space Telescope. It’s great to be able to work in both visual and infrared. Being capable of dealing with infrared will help to study the red light of the universe.
