Space question
How to find other galaxies?
Asked by Yikai
The James Webb Space Telescope (JWST) can find other galaxies by using its infrared sensors to detect the light that these distant galaxies emit. This light has been stretched out (or \"redshifted\") into infrared wavelengths due to the expansion of the universe. JWST's large mirror and high sensitivity also allow it to see very faint and distant galaxies. Additionally, it uses techniques like spectroscopy to study the characteristics of these galaxies.
