Question

Colliding galaxies quick check

Answer 1

Colliding galaxies occur when two or more galaxies collide, resulting in a dramatic and violent event. During these collisions, tidal forces cause elongation and distortion of the galaxy shapes, leading to the formation of new stars and often triggering intense bursts of star formation. The collision can also cause gas and dust clouds to collide and collapse, forming new clusters of stars.

Overall, colliding galaxies are important events in the life cycle of galaxies, as they can significantly affect their structures and star formation rates.
