Arp 147 (also known as IC 298) is an interacting pair of ring galaxies. It lies 430 million [4] to 440 million light years away in the constellation Cetus and does not appear to be part of any significant galaxy group. [3] The system was originally discovered in 1893 by Stephane Javelle [5] and is listed in the Atlas of Peculiar Galaxies.

Arp 147（IC 298）是一对相互作用的环形星系。 它位于4.3亿至4.4亿光年之外的鲸鱼座，似乎并不是任何重要星系群的一部分。 这个星系最初是由Stephane Javelle于1893年发现的，列在特殊星系图集中。

2011年2月14日 · Arp 147 contains the remnant of a spiral galaxy (right) that collided with the elliptical galaxy on the left. This collision has produced an expanding wave of star formation that shows up as a blue ring containing in abundance of massive young stars.

Arp 147 is one of 338 oddball galaxies compiled by astronomer Halton Arp in a book called the Atlas of Peculiar Galaxies. Many of the images in the book, published in 1966, shows what happens when galaxies pass by each other too closely. The gravity of one galaxy tugs on another galaxy, stretching it and creating an irregular shape.

2008年10月30日 · Arp 147 appears in the Arp Atlas of Peculiar Galaxies, compiled by Halton Arp in the 1960s and published in 1966. This picture was assembled from WFPC2 images taken with three separate filters. The blue, visible-light, and infrared filters are represented by the colors blue, green, and red, respectively.

This blue galaxy is part of the interacting galaxy system known as Arp 147, and shows a ring because it has recently collided with the other galaxy in the frame, the red galaxy on the left. Unusually, even this red galaxy shows a ring like band, although it is seen nearly edge-on.

This image shows an indistinct but unique-shaped colliding galaxy pair positioned at 3.6 degrees southeast of alpha Ceti (Menkar). A ring-shaped IC298 has a size of 0.5 arc minutes and another one next to the east is IC298A as a collided companion. Both have brightness of at most 14th or 15th magnitude, not subjects to amateur's observation.

美国国家航空航天局(NASA)的钱德勒X射线天文望远镜和哈勃太空望远镜收集到一组数据，显示距地球约4.3亿光年的一对互扰星系Arp 147产生巨大的黑洞光坏，如同太空中的宝石项链一样光芒耀眼。

We have produced a combined stellar and gasdynamical computer model of a pair of interacting galaxies which exhibits many of the features seen in Arp 147. In our model, the ring forms in a disk galaxy following the passage of an equal-mass elliptical galaxy approximately perpendicular through the disk, about two radial scale lengths from the ...
