Left: black and white, wide-field view of two galaxies colliding. Right: Hubble image of the two galaxy cores, intertwined. The cores are bright yellow-orange. Sweeping around the cores are bright bluish-purple areas of star formation. Rusty-brown clouds and filaments give them a knotted appearance.

C60 & C61: The Antennae Galaxies

A ground-based telescopic view on the left shows the long tails of the Antennae galaxies. On the right, a natural-color image taken by Hubble in 1996 shows the respective cores of the twin galaxies (the orange blobs) crisscrossed by filaments of dark dust. A wide band of chaotic dust, called the overlap region, stretches between the cores of the two galaxies.
