NGC 4261 is an elliptical galaxy [8] located around 100 million light-years [9] away in the constellation Virgo. It was discovered April 13, 1784, by the German-born astronomer William Herschel. [10] The galaxy is a member of its own somewhat meager [11] galaxy group known as the NGC 4261 group, [8] which is part of the Virgo Cluster. [10 ...

天文学家在无线电波段可以观察到ngc 4261从核心发射出的两个突出的喷流。ngc 4261有一个活跃的星系核，其中有一个稍微偏离核心中心的超大质量黑洞 [11] 。黑洞的质量估计为 (1.62 ± 0.04) × 10 9 m ☉ [12] 。

NGC4261是一个射电星系，直径约为60000光年，视星等为10.3等，距离地球大约100000000光年，其形状为E1型旋涡星系。 该星系在许多方面来看都是一个典型的 射电星系，同时还是 椭圆星系 中为数不多的几个具有内部结构的 活动星系 之一。 哈勃太空望远镜 的红外照片穿透了前方遮挡视线的星云，揭示出了一个异常致密的尘埃盘，其中的物质正在沿螺旋轨道朝着星系中心的黑洞下落。 大多数椭圆星系相对而言尘埃含量都很少，那么NGC 4261中的尘埃是从哪里来的呢？ 最 …

おとめ座銀河団の南端部に相当し，最も大きな楕円銀河・ngc4261は長径4分強です。 この写真に写っている15個以上の銀河のほとんどはおとめ座銀河団の外縁部に分布しますが，画面下部のNGC4273などは1億3000万光年の遠距離に位置し，一部は銀河団に属してい ...

The largest elliptical galaxy, NGC4261, is located at the southern edge of the Virgo cluster and has a major axis of just over 4 arc minutes. Most of the 15 or more galaxies in this image are distributed in the outer edge of the Virgo Cluster, but NGC4273, for example, in the lower part of the image is located 130 million light years away, and ...
