NGC 4567 and NGC 4568 (nicknamed the Butterfly Galaxies [4] or Siamese Twins [NB 1] [5]) are a set of unbarred spiral galaxies about 60 million light-years away [1] in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo Cluster of galaxies.
NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy. [6] Much speculation exists in literature as to the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot adjudge among various options put forth.
NGC 4564 is an elliptical galaxy located about 57 million light-years away [2] in the constellation Virgo. [3] NGC 4564 was discovered by astronomer William Herschel on March 15, 1784. [4] The galaxy is also a member of the Virgo Cluster. [5] [6] NGC 4564 has an estimated population of 213 ± 31 globular clusters. [7]
Messier 90 (also known as M90 and NGC 4569) is an intermediate spiral galaxy exhibiting a weak inner ring structure about 60 million light-years away in the constellation Virgo. It was discovered by Charles Messier in 1781.
NGC 4567 and NGC 4568 Also known as the Butterfly Galaxies , NGC 4567 and 4586 are two unbarred spiral galaxies that are colliding. The pair were first discovered by astronomer William Herschel in 1784, but did not earn their name until observer Ralph Copeland called them the Siamese Twins in the late 1800s due to their almost identical shape ...

Messier 89 (M89 for short, also known as NGC 4552) is an elliptical galaxy in the constellation Virgo. It was discovered by Charles Messier on March 18, 1781. M89 is a member of the Virgo Cluster of galaxies .
NGC 4656/57 is a highly warped edge-on [3] barred spiral galaxy located in the local universe 30 million light years away from Earth in the constellation Canes Venatici. [4] This galaxy is sometimes called the Hockey Stick Galaxy or the Crowbar Galaxy. Its unusual shape is thought to be due to an interaction between NGC 4656, NGC 4631, and NGC ...
