NASA’s Hubble Space Telescope has clicked yet another cosmic wonder — an interaction event of two galaxies that are so closely intertwined that they are collectively labeled as a single entity. Galactic interactions are not a rare phenomenon. In fact, a large number of galaxies show some form of interaction either with their satellites or on a much larger scale with other galaxies. The latter category can include events such as collisions that end up in a merger of galaxies or lead to bursts of star formation.
