The telescope has been in development for 14 years. Its launch was postponed several times. James Webb will orbit the sun. Over the course of four weeks, the telescope will move to the second Lagrange point, which is 1.5 million km from Earth. Scientific collection of information will begin at the destination.
The diameter of the James Webb mirror is 6.6 meters. This is more than the other famous Hubble telescope – 2.4 meters. The new scientific instrument will operate for at least five years. The project budget was about $ 10 billion.
Among the tasks of “James Webb” – the detection of light from the first stars and galaxies, the study of the origin of life, the search for exoplanets with a temperature similar to that of the Earth.
