ISO: Normal Galaxies Results Gallery

Colour-composite of the LW2 and LW3 maps of the Antennae Galaxies. Blue indicates a high LW3 to LW2 ratio; red a low ratio

To ISO's penetrating infrared eye, one of the Antennae galaxies shows a large ring of intense starmaking around the central nucleus. This feature is absent in the other galaxy. Another region of star formation extends along a line marking the overlap of the disks of the two galaxies, where the collision is fiercest.
