Here is a brief intro on why at least from a physics standpoint, the name can be considered ironic:

Its peculiar appearance is the result of a collision between two similar gas-rich disc galaxies that took place about 600 million years ago, which ripped both galaxies apart.

Perhaps there is peace within the galaxy and we just don’t understand it because we’re describing it from this vantage point 😉

Here is a great video on this interesting formation:

European Southern Observatory astronomers have produced a spectacular new image of the famous Atoms-for-Peace galaxy (NGC 7252). This galactic pile-up, formed by the collision of two galaxies, provides an excellent opportunity for astronomers to study how mergers affect the evolution of the Universe.
