A Zoo of Galaxies

Galaxies come in all shapes and sizes. The differences between them hints at their formation, and at the assembly of the universe.

Visible: To Hubble's visible-light-detecting cameras, galaxies look like a continuum of shapes and sizes from grand spirals to indistinct ellipticals.

Far-infrared: Viewed by the European Space Agency's Herschel Space Observatory, only certain galaxies have dense cores, which can be seen only in the infrared. This sequence of galaxies would look very different under Webb's powerful infrared vision, which would bridge the gap between these two images.
