Fully used James-Webb space telescope

The James-Webb Space Telescope, with its main mirror, successfully completed the last phase of its deployment on Saturday, January 8th. It is now in its final stages, and in more than five months, it will be able to begin its study of the universe.

The iconic main glass of the telescope was 6.5 meters in diameter, so it was too large to fit on a rocket. On departure, Two weeks ago. So both its sides should be folded backwards.

The first of those two wings was used on Friday and the second was opened as scheduled on Saturday morning, NASA said.

However, before operation, the telescope must still reach its final orbit of 1.5 million kilometers from Earth, and must be continuously cooled before scientific instruments can be measured very accurately.

James-Web, the most powerful space laboratory ever designed, should make it possible for the Big Bang to observe the first galaxies that formed about 200 million years later.
