In this composite image of the merging cores of the Antennae Galaxies, optical (white and pink), radio (blue) and millimeter/submillimeter (orange and gold) overlay to show us the history and future of star formation. The optical image shows stars that are shining now. The radio shows gas that is probably too thin to become stars. And the mm/submm shows all the places where new stars will someday form.
