NASA's Webb Reveals Astonishing Structures in 19 Galaxies

6 Min Read

Nineteen Webb images of face-on spiral galaxies are combined in a mosaic. Some appear within squares, and others horizontal or vertical rectangles. Many galaxies have blue hazes toward the centers, and all have orange spiral arms. Many have clear bar shaped-structures at their centers, but a few have spirals that begin at their cores. Some of the galaxies' arms form clear spiral shapes, while others are more irregular. Some of the galaxies' arms appear to rotate clockwise and others counterclockwise. Most galaxy cores are centered, but a few appear toward an image's edge. Most galaxies appear to extend beyond the captured observations. The galaxies shown, listed in alphabetical order, are IC 5332, NGC 628, NGC 1087, NGC1300, NGC 1365, NGC 1385, NGC 1433, NGC 1512, NGC 1566, NGC 1672, NGC 2835, NGC 3351, NGC 3627, NGC 4254, NGC 4303, NGC 4321, NGC 4535, NGC 5068, and NGC 7496.
