The Spindle Galaxy (sextans) (スピンドル銀河) NGC3115

This photo shows the Spindle galaxy of NGC 3115 in the southern sextans, not the NGC 5886 in the northern Draco.
They have the same name and are slightly different in color but similar in appearance. However, the decisive difference is that this NGC3116 does not have a dark band running in the center.
It can be said that a galaxy is characterized by having no features in visible light photographs.
It seems that there is a huge black hole in the center of basil, which is 2 billion times the mass of the sun.

この写真は北のりゅう座にあるNGC5886では無く南の六分儀座にあるNGC3115のSpindle銀河である。
同じ名前だけあって色は多少違うが容姿は似ている。ただ決定的な違いはこのNGC3116には中央部を走る暗黒帯が無い。
可視光の写真ではとても特徴がないのが特徴の銀河と言って良いだろう。
バジルの中心には太陽の20億倍という質量の巨大Black Holeがあるらしい。
