How can we take pictures of other galaxies?

Answer 1

The light from far way galaxies is very faint.So we have to use very large telescopes and expose for long time to get enough photons to have clear picture.The earth moves so we have to use telescopes with drive whci compensate earth's motion.

Because Hubble and other space telescopes operate above the earth's atmosphere and are not affected by atmospheric disturbances, they are able to capture better images.

To capture images of other galaxies, astronomers use powerful telescopes equipped with specialized instruments, such as cameras and sensors sensitive to various wavelengths. Observatories located in space, like the Hubble Space Telescope, provide clearer views by avoiding Earth's atmosphere. Long-exposure techniques and image processing enhance the visibility of distant galaxies.
