The most powerful space telescope reached the target after 30 days

The second Lagrange point (L2) has been reached by NASA’s James Webb Space Telescope, which has covered a distance of about 1.6 million kilometres from Earth in a month. NASA, the United States’ space agency, announced the news on social media. NASA, the European Space Agency, and the Canadian Space Agency collaborated on the development of this telescope.

What is Lagrange Point, and how does it work?

The distance at which the gravitational effect of the Earth and the Sun on any object remains constant is known as the Lagrange point. As a result, the object becomes more stable, and fuel consumption decreases. However, NASA has stated that this point is not completely stable as well. L1, L2, L3, L4, and L5 are the five Lagrange points between the Earth and the Sun. Lagrange point is named after Joseph Louis Lagrange, a French mathematician.

The L2 point, or second Lagrange point, is the most ideal location. The equipment in the telescope will not get too hot at this location. In addition, the gravitational balance at this point is greater than at other locations. NASA will use this location to test its optics and other instruments. After that, it will get down to business.

The previous year’s launch coincided with the holiday season.

It has 100 times the power of the Hubble Space Telescope, which was launched in 1990.

An Ariane rocket from a launching base in French Guiana launched the James Webb Space Telescope on December 25 of last year. This has cost around 75 thousand crores of rupees. This is the world’s most powerful telescope. Its capability is demonstrated by the fact that it can easily detect a bird flying over the earth from space.

A thin layer of gold has been applied to the telescope’s optics. The infrared light will be deflected by this layer, keeping the telescope cool. A tennis court-sized 5-layer sunshield has been installed to protect the cameras from the sun’s heat. The telescope has a diameter of 21 metres. It has 100 times the power of the Hubble Space Telescope, which was launched in 1990. Galaxies, meteorites, and planets formed in the early universe can all be detected using this method.
