James Webb Telescope reached 1.6 Million Km away from Earth will now reveal the Secrets of the Universe
NASA’s James Webb Space Telescope has reached its final stable point, the second Lagrange point (L2), covering a distance of about 1.6 million kilometers from Earth in a month. The US space agency NASA has given information about this through a social media post. This telescope has been developed by NASA, the European Space Agency and the Canadian Space Agency.
What is Lagrange Point?
Lagrange point is the distance at which the gravitational effect of the Earth and the Sun on any object remains the same. Due to this the object becomes stable and the fuel consumption is reduced. However, it has been said from NASA that this point is not completely stable either. There are five Lagrange points between the Earth and the Sun, called L1, L2, L3, L4 and L5. Lagrange point is named after the French mathematician Joseph Louis Lagrange.
The second Lagrange point or L2 point is the most ideal place. At this place the equipment in the telescope will not get too hot. Along with this, the gravitational balance at this point remains more than at other points. Here NASA will check its optics and other instruments. After which it will start its further work.
The James Webb Space Telescope was launched on December 25 last year by an Ariane rocket from a launching base in French Guiana. About 75 thousand crore rupees have been spent on this. This is the most powerful telescope in the world. Its capability can be gauged from the fact that it can also easily detect a bird flying on the earth from space.
The optics of the telescope have been coated with a fine layer of gold. This layer will deflect infrared light, keeping the telescope cool. To protect the cameras from the heat of the sun, a tennis court-sized 5-layer sunshield has been installed in it. The diameter of the telescope is 21 meters. It is 100 times more powerful than the Hubble telescope sent in 1990. Through this, galaxies, meteorites and planets formed in the early period of the universe can also be detected.
