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.


Also NGC 3729 is a spiral galaxy located about 70 million light-years away in the constellation Ursa Major. It has a relatively small size, with a diameter of about 50,000 light-years. 

One of the most interesting features of NGC 3729 is its compact, bright nucleus. The nucleus is thought to be a site of active star formation, with young, massive stars being born at a high rate. This is supported by observations of strong radio and infrared emission coming from the nucleus.

NGC 3729 also has a prominent bar-shaped structure in its center, which is believed to be the result of a gravitational interaction with another galaxy. The bar is surrounded by tightly-wound spiral arms that extend out from the center of the galaxy.

One unusual feature of NGC 3729 is its asymmetric shape. The galaxy appears to be slightly elongated and tilted, with one side of the disk extending further out than the other. This could be the result of a past interaction with another galaxy that caused NGC 3729 to become distorted.

Overall, NGC 3729 is an interesting object for astronomers to study because it provides insights into the complex interactions and processes that shape the structure and evolution of spiral galaxies like our own Milky Way.

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.
