NGC 1553 is a prototypical [3] lenticular galaxy in the constellation Dorado. It is the second brightest member of the Dorado Group of galaxies. [4] [5] [6] [dubious – discuss] British astronomer John Herschel discovered NGC 1553 on December 5, …

NGC 1553 是 剑鱼座 的一個 星系。

NGC 1553 is a Spiral Galaxy located in the constellation of Dorado in the southern hemisphere. NGC 1553's distance from Earth is 49,288,751.80 light years. NGC 1553 is called NGC 1553 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.

2023年10月2日 · Physical Information: Based on a recessional velocity of 1080 km/sec, NGC 1553 is about 50 million light-years away, in good agreement with widely varying redshift-independent distance estimates of 25 to 75 million light-years. Given that and its apparent size of about 7.5 by 6.2 arcmin (from the images below), it is about 110 thousand light ...

2025年1月20日 · NGC 1553是剑鱼座星系团的主要成员之一，该星系团还包括椭圆星系NGC 1549以及其他星系如NGC 1546等。 这些星系之间由于互相的引力作用，周围环绕着非常显眼的潮汐流与潮汐壳。 有观测研究指出，NGC 1553中可能存在壳状或潮汐特征，但这些特征都位于较大的半径处。 此外，尽管在螺旋区域观测到了特定的气体冷却现象，但星系中的气体压力平衡状态仍是一个复杂的问题。

Chandra's detection of numerous neutron stars and black holes in this and other elliptical galaxies shows that these galaxies once contained many very bright, massive stars, in marked contrast to the present population of low-mass faint stars that now dominate elliptical galaxies.

The optical image of NGC 1553 fades into the corresponding Chandra X-ray image. NGC is about 70 million light years away in the constellation of Dorado.Anima...
