Question

1. which of the following is going through \galactic cannibalism\ or galaxy mergers? four options with images of galaxies

Explanation:

Galactic cannibalism/mergers occur when two or more galaxies interact gravitationally, distorting each other's shapes, often showing connected tidal tails or distorted spiral structures. The first image shows two distinct galaxies close together with distorted shapes, and the second shows a galaxy with a prominent tidal tail, both signs of ongoing merger activity.

Answer:

1. The top image (two interacting distorted galaxies)
2. The second image (galaxy with a tidal tail)
