Interacting galaxy
Videos
Interacting galaxies, also known as colliding galaxies, are two or more galaxies whose gravitational fields result in a disturbance of one another. There are several types of galactic interactions, in
NGC 3169 (left) and NGC 3166 (right), located in the constellation Sextans display some curious features, showing that both galaxies are close enough to feel the distorting gravitational influence of the other.

Antennae Galaxies

The Antennae Galaxies are a pair of interacting galaxies in the constellation Corvus. They are currently going through a starburst phase, in which the collision of clouds of gas and dust, with entangl
