The background color image shows a map of the light intensity (redder color shows stronger Emission) in the core region of the protogalactic cluster A2744ODz7p9, acquired with the NIRCam onboard JWST. The size of the image corresponds to about half of the radius of the Milky Way Galaxy. (Left) Contours show the distribution of light emitted by ionized oxygen, obtained with the NIRSpec instrument onboard JWST. 4 galaxies were identified at 13.14 billion light-years away. (Right) Contours show the distribution of dust emission from three of the four galaxies. The white circle in the lower left of the figure indicates the beam size of the ALMA data.
