Hubble image of Arp 220, also known as IC 4553.

Arp 220 is the aftermath of a collision between two spiral galaxies. The collision set off a burst of star formation, creating star clusters seen as bluish-white bright knots in this image.

This image is part of a collection of 59 images of merging galaxies released to celebrate Hubble's 18th anniversary in 2008.

Hubble Interacting Galaxy Arp 220

Arp 220 appears to be a single, odd-looking galaxy, but is in fact a nearby example of the aftermath of a collision between two spiral galaxies. It is the brightest of the three galactic mergers closest to Earth, about 250 million light-years away in the constellation of...
An irregularly shaped galaxy fills most of the frame. The center is brighter, filled with a blue-white haze of stars that backlights a horizontal band of brown dust. Another area to the left of the core, almost as bright as the center is filled with a similar haze of stars and dotted with blue star clusters. To the right, the galaxy is less bright and more transparent. A faint hazy line extends almost vertically from the top of the galaxy. The black background of space is filled with stars and tiny background galaxies.
