March 16, 2009--Two hearts are about to become one in a rare picture of galaxies colliding.

The bright object NGC 6240 is actually a pair of galaxies tangled together in a late phase of their evolution just before they merge. The cores of the two galaxies, still visible as separate points, are hurtling toward each other and will likely combine in just a few million years.

The galactic "train wreck" is generating huge amounts of heat, seen above as visible and infrared light in combined images from the Hubble and Spitzer space telescopes.
