Hubble Interacting Galaxy II Zw 96
About This Image
This is a system of merging galaxies with a bizarre shape. Powerful young starburst regions hang as long threadlike structures between the main galaxy cores. The system almost qualifies as an ultra-luminous system, but has not yet reached the late stage of coalescence that is the norm for most ultra-luminous systems. II Zw 96 is located in the constellation of Delphinus, the Dolphin, about 500 million light-years away from Earth.
This image is part of a large collection of 59 images of merging galaxies taken by the Hubble Space Telescope and released on the occasion of its 18th anniversary on 24th April 2008.

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
