The James Web Telescope, which is slated to launch in November as a replacement for the Hubble Telescope, is unique in that it’s mainly infrared sensors. While Hubble relies heavily on (and has a small infrared sensor) optical light, this telescope mainly tries to see the universe in high-wavelength infrared. Why is it so popularly known as the Time Machine, which cost billions of US dollars? If we look at the Andromeda Galaxy in a telescope, we see a galaxy 2.5 million years old. This telescope can see objects 13.5 billion years behind, that is, 13.5 billion years behind. Many will have to be demolished. Because we are going to see the beginning of the universe.
