      Distant galaxies appear as yellow blurry dots while a few nearby bright   
       stars appear in white and surrounded by spikes caused by diffraction.

      Explanation: Gravitational lensing by the galaxy cluster MACS0647 -- in   
      which the massive foreground cluster distorts and lenses the light   
      emitted by distant background galaxies along the line of sight -- is on   
      vivid display here in this recent multi-color infrared image from the   
      James Webb Space Telescope (JWST). In particular, the background source   
      MACS0647-JD is seen to be lensed three times by the cluster. When first   
      discovered with the Hubble Space Telescope, MACS0647-JD was observed as   
      an amorphous blob. With Webb though, this single source is revealed to   
      be a pair or small group of galaxies. The colors of the MACS0647-JD   
      objects are different as well -- indicating differences potentially in   
      the age or dust content of these galaxies. These new images provide   
      rare examples of galaxies in an era only a few 100 million years after   
      the Big Bang.
