Three spiral galaxies, an elliptical galaxy, and a lenticular (or, lens-like) galaxy are huddled together 300 million light years away within less than twice the width of the Milky Way’s disk. They are in physical conversation with one another, interacting with their neighbors’ gravity and slightly warping as a result. Their relationship could teach astronomers a lot about how galaxies formed.
