Photo description / processing
NGC 3718 is a distorted spiral galaxy in the constellation Ursa Major. It is located approximately 59 million light-years from Earth. Its main feature is its warped structure: the spiral arms are asymmetrical, and a dust lane, twisted into an almost S-shape, is visible at its center.
Scientists believe the unusual shape is the result of gravitational interaction with the neighboring galaxy NGC 3729. These two objects are connected by invisible "threads" of mutual attraction, which have been distorting their structures over millions of years. They are part of the Ursa Major Cluster—a group of galaxies bound by a common motion through space.
If you look carefully at the area near NGC 3718, you can notice a cluster of elongated smudges. This is Hickson 56—a compact group of 5 galaxies that are much farther away, approximately 400 million light-years from us. They are positioned very close to each other and are likely on a path toward a future merger.
