   Explanation: Bright at infrared wavelengths, [4]this merging galaxy
   pair is some 500 million light-years away toward the constellation
   Delphinus. The [5]cosmic mashup is seen against a background of even
   more distant galaxies, and occasional spiky foreground stars. But the
   galaxy merger itself spans about 100,000 light-years in this deep
   [6]James Webb Space Telescope image. The image data is from Webb's
   Near-InfraRed Camera ([7]NIRCam) and Mid-InfraRed Instrument ([8]MIRI).
   Their combined, sharp infrared view follows galactic scale
   [9]restructuring in the dusty merger's wild jumble of intense star
   forming regions and distorted spiral arms
