This image of Arp 107 reveals the supermassive black hole that lies in the center of the large spiral galaxy to the right.

Perhaps the defining feature of the region are the millions of young stars that are forming, highlighted in blue. These stars are surrounded by dusty silicates and soot-like molecules known as polycyclic aromatic hydrocarbons. The small elliptical galaxy to the left, which has already gone through much of its star formation, is composed of many of these organic molecules.
