Peculiar Galaxy NGC 3256 in Vela | NASA's Chandra X-ray Observatory
A pair of colliding, gas-rich spiral galaxies merging into a single massive system. Chandra’s X-ray data (pink) isolates point sources and shock-heated gas, Hubble’s optical light (blue and white) captures tidal tails of stars, and Webb’s infrared vision (red and orange) cuts through the dust to show hidden star formation. Galaxy collisions like this offer a preview of our far future, showing what might happen if our own Milky Way collides and merges with the nearby Andromeda Galaxy.
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.
