Wouldn't it be great if we could see the period in the history of the Universe that is hidden from us? This and many others will soon be tackled by the James Webb Space Telescope.

James Webb telescope

The main task of the telescope is to detect the light of the first stars and galaxies formed after the Big Bang. It is for this purpose that NASA, in cooperation with the European and Canadian Space Agencies, is working on the early launch of James Webb into orbit.

Here are 10 interesting facts about this next-generation telescope:

1. The James Webb Space Telescope is the world's largest orbiting infrared observatory to replace the Hubble telescope. Following his predecessor, James Webb will continue to study the formation and development of galaxies, stars, planetary systems and the origin of life.

2. The telescope is named after the second head of NASA, James Webb, who headed the agency from 1961 to 1968.

3. "James Webb" can boast not only of its gigantic size (as high as a three-story house and as long as a tennis court), but also for its power. NASA claims that in this component it bypasses the Hubble a hundred times!

4. The new generation telescope is so large that it will have to be folded like origami to fit into a rocket that is 5.4 meters wide. After James Webb reaches its destination, its segments will be revealed one by one.

5. James Webb will conduct infrared observations with unprecedented sensitivity. This will allow him to see the first galaxies that formed after the Big Bang over 13.5 billion years ago.

6. Infrared cameras of the telescope are so sensitive that they must be protected from the light of the Sun, Earth and Moon.

7. "James Webb" will be placed in a halo orbit at the Lagrange point L2 the Sun-Earth system, where it will operate at temperatures below –235 ° C.

8. 18 hexagonal mirrors of the telescope with a total diameter of 6.5 meters are covered with a thin layer of gold to optimize their reflectivity in the infrared range.

9. According to the plan, the launch of "James Webb" will take place in 2018 from the Kourou launch site in French Guiana. Presumably, the telescope will be launched using the Ariane-5 rocket.

10. The James Webb Space Telescope is an international project led by NASA, ESA and CSA. Once commissioned, scientists from all over the world will be able to use the telescope to study our solar system, planets beyond, as well as stars and galaxies.
