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.
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 ...
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 4647 is an intermediate spiral galaxy estimated to be around 63 million light-years away [2] in the constellation of Virgo. [3] ... NGC 4567 and NGC 4568; References

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 4676, or the Mice Galaxies, are two spiral galaxies in the constellation Coma Berenices. About 290 million light-years distant, [ 2 ] they have begun the process of colliding and merging. Their "mice" name refers to the long tails produced by tidal action —the relative difference between gravitational pulls on the near and far parts of ...
