Paul Hickson lists this group of galaxies in his 1993 «Atlas of Compact Groups of Galaxies" as HCG 92. He wrote: «This is the famous group of Stephan's Quintet, also Arp 319 and VV 228. It consists of a compact quartet plus a bright, lower redshift, spiral galaxy (NGC 7320).

HCG 92, also known as Stephan's Quintet, is a compact group of galaxies located in the constellation Pegasus. I imaged this group of very small galaxies from a Bortle 4 zone, and made sure to frame my shot so that a much larger object, NGC 7331would also be …

Four of the five galaxies in Stephan's Quintet form a physical association, a true galaxy group, Hickson Compact Group 92, and will likely merge with each other. Radio observations in the early 1970s revealed a filament of emission between the galaxies in the group.

The most famous group on Hickson's list of 100 objects is HCG 92, Stephan's Quintet. According to Hickson: “Most compact groups contain a high fraction of galaxies having morphological or kinematical peculiarities, nuclear radio and infrared emission, and starburst or active galactic nuclei (AGN) activity.

2018年12月14日 · In 1982, Canadian astronomer Paul Hickson designated these four as HCG 92 (Hickson Compact Group 92) in his catalog of compact galaxy clusters. Located at a distance of about 300 million light years, the foursome is oriented diagonally in the accompanying picture.

About 9h of LRGB data. This is one of my favorite targets. It fits well in my field of view, is well-balanced artistically, and has many physical complexities. NGC-7331 has some interesting asymmetric...

HCG 92はペガスス座にある小型銀河群。 発見したエドゥアルド・ステファンの名前から「ステファンの5つ子」と呼ばれます。 その名の通り、5つの銀河が集まって見える場所です。 5つの銀河の内4つは、互いに引っ張り合っており、銀河の中のガスや星が引きはがされていいます。 これらはいずれは一つにまとまってしまうと考えられます。 残りの1つは、実は他の4つとは関係が無く、ずっと近い所にあります。 「5つ子」は見かけだけのことなのです。 手前の銀河まで …
