Hubble Interacting Galaxy NGC 3256

Hubble Interacting Galaxy NGC 3256

NGC 3256 is an impressive example of a peculiar galaxy that is actually the relict of a collision of two separate galaxies that took place in a distant past. The telltale signs of the collision are two extended luminous tails swirling out from the galaxy. NGC 3256 belongs to the Hydra-Centaurus supercluster complex and provides a nearby template for studying the properties of young star clusters in tidal tails. The system hides a double nucleus and a tangle of dust lanes in the central region. The tails are studded with a particularly high density of star clusters.

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

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    10h 27m 51.57s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.

  • Distance
    DistanceThe 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.
    100 million light-years (50 million parsecs)
