Difference between Andromeda Galaxy and H II region

Andromeda Galaxy vs. H II region

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way. An H II region or HII region is a region of interstellar atomic hydrogen that is ionized.
