When two galaxies come close to each other, the gravitational forces between them can cause them to distort and deform. In the case of the tadpole galaxy, it is believed that the gravitational forces from the nearby galaxy have pulled material out of the galaxy, creating the long, thin tail-like structure.
This type of interaction is known as "tidal stripping," and it is thought to be responsible for the formation of many other tail-like structures in galaxies. As the two galaxies continue to interact, the tidal forces can cause more material to be pulled out of the tadpole galaxy, further elongating the tail.

Sorry about that. Is the Globular cluster Messier 3.
