NASA launches new space telescope "James Webb" into orbit (video)


After 14 years of development, NASAlaunched the new James Webb Space Telescope from the European Kourou Cosmodrome in French Guiana on the Arianespace Ariane 5 rocket. The launch took place on Christmas Day, 25 December.

The James Webb Space Telescope (JSWT) willrevolve around the Sun, close to the second Lagrange point in the Earth-Sun system. It will take about a month to enter a given orbit, after which researchers can begin observing black holes, studying some of the oldest galaxies in the universe and assessing the habitability of various exoplanets.

Participated in the development and creation of JSWTEuropean and Canadian space agencies. This is one of the most expensive NASA projects, which began back in 2007. However, a change in design, technical conditions, and even a coronavirus pandemic led to numerous delays in the start of the program worth over $ 10 billion.


The James Webb telescope has a mirror diameter of 6.6meters, which is much more powerful than its "brother" - the Hubble telescope with a mirror with a diameter of 2.4 meters. The JSWT telescope has a gold-plated mirror array that can collect seven times more light than the Hubble and scan the infrared spectrum to "see" through the dust. As a result, NASA astronomers hope to "see" the ancient regions of the universe as they were 13 billion years ago.
