This time we return to the galaxies with not too often imaged ones…Twin galaxies NGC 4567/68 & M58NGC 4567&4568This pair of Spiral Galaxies in Virgo is known as "The Siamese Twins" or "The Butterfly Galaxies". Both are classic spiral galaxies with small bright nuclei, several knotty arms, and arm segments. Both also have a hint of an inner ring. The pair is probably a member of the Virgo Galaxy Cluster.Since they both have nearly the same red shift they may well be very close or in actual contract. However, other than a dim general x-ray glow involving both galaxies there is no indication of interaction. Neither galaxy is distorted nor are there any tidal tails. If they are in contract their orbital dynamics is such that they have not become distorted. Based on their red shifts they are roughly 120 million light years away (Hubble Constant of 62 Km per sec., per Megaparsec) and at that distance the projected distance between their nuclei is only 45,200 light years Messier 58 - M58 - Barred Spiral Galaxy      SAB(rs)6M58 is a magnitude +9.8 barred spiral galaxy that's one of the brightest members of the Virgo cluster. At a distance of 68 million light-years it's one of the furthest objects in the Messier Catalogue, but bright enough to be visible in large binoculars and small telescopes. Although not realised at the time of discovery, M58 was the most distant object - up to that date - ever observed. It's best seen during the months of March, April and May.The centre of the Virgo cluster is positioned approximately halfway along a line connecting Denebola (β Leo - mag. +2.1) to Vindemiatrix (ε Vir - mag. +2.8). M58 is located a few degrees southeast of the central region. Positioned a degree east of M58 are M59 and M60, with M89 located a degree northwest of M58.Along with M91M95 and M109, M58 is one of four barred spirals in the Messier catalogue.M58 has an active galactic nucleus, which contains a supermassive black hole and some starburst activity. Two supernovae have been observed in M58, a type II at mag. +13.5 in 1998 and a mag. +12.2 type I a year later.If you explore the full image you can found also a multitude of other galaxies, biggest is NGC 4564 near center, even more than Mag 22
