SEWAKTU.com — The James Webb Telescope is a space telescope made by NASA, the United States Space Agency. The purpose of this orbiting telescope is to study the universe.
It is known, this telescope is designed to be a replacement for the Hubble telescope and will become the most powerful telescope in the world shortly after launch.
The size of the James Webb telescope has a main mirror with a diameter of 6.5 meters, larger than the main mirror of the Hubble Telescope which is 2.4 meters in diameter.
The telescope will be equipped with more sophisticated and sensitive instruments, allowing it to look deeper into the universe’s past and learn more about the origin of the universe, the stars, planets and life in the universe.

One of the main goals of the James Webb Telescope is to study the early universe and help us better understand how galaxies, stars and planets formed.
The telescope will also study the atmospheres of planets outside our solar system and look for signs of life on other planets.
The James Webb Telescope has discovered several galaxies
The James Webb Space Telescope continues to showcase the best great discoveries about how the universe evolved, thanks to its uncanny ability to see farther back in time and space than ever before.
Several very large galaxies have now been discovered that contain more mass than was thought to exist in the entire universe at the time.
Because the speed of light in a vacuum is constant, we observe objects in space with a delay in time. The sun is eight light minutes away, so we see it as it did eight minutes ago.

The next closest star, Alpha Centauri, is about four light years away, so our view of it is four years too late.
If we extend that principle to the deepest reaches of space, it’s really possible to look back billions of years, get a glimpse of how galaxies evolved over the lifetime of the universe.
