Which galaxy is known as an example of a spiral galaxy besides the Milky Way?

Andromeda is a well-known example of a spiral galaxy, and it is the nearest spiral galaxy to the Milky Way. It is situated about 2.537 million light-years from Earth and is part of the Local Group of galaxies. The Andromeda Galaxy, also known as M31, features a bright central core, winding arms filled with stars, gas, and dust, which are characteristic traits of spiral galaxies. Its size and structure make it a prominent object in the night sky and a subject of study for astronomers, enhancing our understanding of galaxy formation and behavior.

While the other choices also represent spiral galaxies, Andromeda retains significant recognition due to its proximity and because it is expected to collide with the Milky Way in approximately 4.5 billion years, making it a critical point of interest in the study of galactic dynamics.
