Asked by Hannah Green
Although we can use both intergalactic and extragalactic to describe areas of space, they do have slightly different definitions. In general we use the word intergalactic when talking about a place in the universe that is located somewhere between two or more galaxies. In comparison to this we can use the word extragalactic to describe anything that can be classified as being outside of the galaxy we reside in, the Milky Way.
