NGC 3718 is a spiral galaxy located about 52 million light-years away in the constellation Ursa Major. It's a relatively small galaxy, with a diameter of only about 80,000 light-years.
One of the most striking features of NGC 3718 is its warped disk. The disk of the galaxy appears to be twisted or bent, with one side of the disk higher than the other. This is thought to be the result of a past gravitational interaction with another galaxy, which caused the disk to become distorted.
NGC 3718 also has an active galactic nucleus, which means that there's a supermassive black hole at its center that's actively accreting matter and emitting energy in the form of radiation. This can cause the galaxy to emit a lot of X-rays and other high-energy radiation.
Another interesting feature of NGC 3718 is its pair of faint, elongated outer arms. These arms are thought to be the result of a tidal interaction with a neighboring galaxy, which caused NGC 3718 to become elongated and stretched out.
Overall, NGC 3718 is a fascinating object to study for astronomers, as it provides a glimpse into the complex interactions and processes that shape the evolution of galaxies over billions of years.
And we can find Hickson 56 galaxy group is a small group of galaxies located about 400 million light-years away in the constellation Ursa Major, near the galaxy NGC 3718. The group contains four main galaxies and several smaller ones, all of which are interacting with each other through their mutual gravity.
The largest galaxy in the group is NGC 3729, which is a spiral galaxy with a bright, compact nucleus and tightly-wound spiral arms. It is surrounded by a number of smaller, irregularly-shaped galaxies that are likely being gravitationally pulled in by NGC 3729.
Another notable member of the group is NGC 3726, which is a barred spiral galaxy with a bright, active nucleus. It is surrounded by a faint, diffuse halo of gas and dust, which is likely the result of recent star formation.
Overall, the Hickson 56 galaxy group is a fascinating object for astronomers to study because it provides insights into the complex interactions and processes that shape the structure and evolution of galaxies in groups and clusters.
