Takeaway Keyway:
- NGC 3718 is a strangely form spiral galaxy, about 65 million light years away.
- Its unusual form is probably due to its interaction with the nearby NGC 3729.
- NGC 3729 is a more typical spiral galaxy, even about 65 million light years away.
- Hickson Compact Group 56 is a group distant of interactive galaxies, much further away than NGC 3718 and 3729.
Ursa Major and her great ASTERISM OF DIPPER are full of fantastic galaxies. Two strange galaxies that live in this area can be found under the southern edge of the Dipper. NGC 3718 (ARP 214) is a distorted barrata spiral that lies about 65 million light years away. He lights up in Magnitune 10.6, extends over 2.9 ‘for 2.3’ and is characterized by a strong S form, a prominent dust bar that surrounds his hub and an intensely bright and concentrated nucleus.
NGC 3718 exhibition Warping which is believed to have been caused by the interaction with its neighbor, NGC 3729, which is located about 150,000 light years from the neighbor.
NGC 3729 is a barred spiral that lies about 65 million light years of distance, which shines with magnitude 11.0, which covers 2.8 “for 1.8” and which represents a spiral structure excluded from the garden.
South of the NGC 3718 is another unusual object, the strange group of interactive galaxy known as Hickson Compact Group 56, which consists of a chain of distant galaxies that lie at about 425 million light years away.
