NGC 922 is a peculiar galaxy in the southern constellation of Fornax. Its velocity with respect to the cosmic microwave background is 2879 ± 15 km/s, which corresponds to a Hubble distance of 138.5 ± 9.7 Mly (42.46 ± 2.98 Mpc). [1] Additionally, 17 non-redshift measurements give a distance of 138.88 ± 7.47 Mly (42.582 ± 2.291 Mpc). [8]

NGC 922 是距離地球1億5千萬光年遠的一個 棒渦星系。 環的結構和扭曲的螺旋臂是3億3千萬年前一個小星系將它當作宇宙射擊的靶心，擊中NGC 922的核心造成的結果 [2]。

2012年12月6日 · NGC 922 lies 157 million light-years away from Earth. Bright pink nebulae almost completely encircle a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy's distorted spiral shape result from a smaller galaxy scoring a cosmic bull's-eye, hitting the center of NGC 922 some 330...

2012年12月6日 · Bright pink nebulae almost completely encircle a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy’s distorted spiral shape result from a smaller galaxy scoring a cosmic bullseye, hitting the centre of NGC 922 some 330 million years ago.

NGC 922是位于 天炉座 的一个 棒旋星系，离地球1.5 亿光年。 星系中的扭曲和环状的结构是由于3.3亿年前一个小 星系 碰撞到了NGC 922的中心造成的。 就像投入池塘的小石子，这次撞击从部分恒星密集的中心，也就是撞击点，向外送出了高密度的气体涟漪。

2012年12月17日 · What is sure is that NGC 922 is a ring galaxy created by the collision of a large and small galaxy about 300 million years ago. Like a rock thrown into a pond, the ancient collision sent ripples of high density gas out from the impact …

NGC 922, located about 157 million light years from Earth, was formed by the collision between two galaxies. One of these galaxies is shown in this composite image with X-rays from Chandra (red) and optical data from Hubble (appearing as pink, blue, and yellow).

We have found the peculiar galaxy NGC 922 to be a new drop-through ring galaxy using multiwavelength (ultraviolet–radio) imaging and spectroscopic observations. Its ‘C’-shaped morphology and tidal plume indicate a recent strong interaction with its companion which was identified with these observations.

2012年12月6日 · An almost complete circle of bright pink nebulae skirts around a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy’s distorted spiral shape result from a smaller galaxy scoring a cosmic bullseye, hitting the centre of NGC 922 some 330 million years ago.
