NGC 4027 (also known as Arp 22) is a barred spiral galaxy approximately 83 million light-years away [2] in the constellation Corvus. It is also a peculiar galaxy because one of its spiral arms goes out more than the other. This is probably due to a galactic collision in NGC 4027's past.

NGC 4027，或稱為 阿普22 （Arp 22），是距離地球約8300萬 光年 的 棒旋星系 [2]，天球上位於 烏鴉座。 NGC 4027因為其中一個螺旋臂較其他螺旋臂向更外側延伸，同時被列為 特殊星系。

2024年12月1日 · NGC 4027, also known as Arp 22, stretches its single extended spiral arm towards north. This peculiar extended arm, thought to be the result of a collision with another galaxy millions of years ago — most likely a small galaxy ESO 572-36, also known as NGC 4027A. NGC 4027 is part of the NGC 4038/9 Group. [221]

NGC 4027 is a Barred Spiral Galaxy in the Corvus constellation. NGC 4027 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

NGC 4027 is a Galaxy located in the constellation of Corvus in the southern hemisphere. NGC 4027's distance from Earth is 39,928,063.76 light years. NGC 4027 is called NGC 4027 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.

NGC 4027 is a barred spiral galaxy located in the constellation Corvus. It is known for its peculiar appearance, featuring a single prominent spiral arm, which makes it quite unique compared to typical spiral galaxies.

One arm of NGC4027 is very small, likely due to a collision with another galaxy in the distant past. This debris is thought to be the triangular-shaped NGC4027A seen below, but the galaxy it collided with seems to have moved away and is no longer in the vicinity.L:108mim (3min x 36), R/G/B: (3minx6)/ (3minx3)/ (3minx5) , 2x2 binning.

NGC 4027 (Arp 22, MCG -3-31-8, ESO 572 37, PGC 37773) is an 11.7 magnitude, face-on spiral galaxy that is interacting with one or more of its fainter neighbors. Its shape is very irregular, extending roughly 3.2' x 2.5'.
