| Using different infrared cameras. |
Stars and Galaxies having a big distance from earth. These are producing light of wavelength in visible range as well as infrared range. Due to light coming from a distant object with facing lots of dust particles the visible range shift towards infrared of light. so dust particles reduce the visibility and reason for the red shift of light. There JWST Telescope uses the infrared camera and with measuring the wave length it prouces a colourful images.
