NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici.

2016年1月5日 · This galactic burping was found in the Messier 51 galaxy, which is located about 26 million light years from Earth and contains a large spiral galaxy NGC 5194 (also known by its nickname of the “Whirlpool”), merging with a smaller companion galaxy NGC 5195.

2024年8月25日 · Hubble’s clear view shows that NGC 5195 is passing behind M51. The small galaxy has been gliding past the Whirlpool for hundreds of millions of years. In Hubble’s captivating image of M51, the red represents infrared light as well as hydrogen within giant star-forming regions.

NGC 5195和漩涡星系是天文学中最著名的相互作用星系之一。 这两个星系被列入特殊星系，作为 旋涡星系 与伴星系的几个突出例子之一。 该系统也是对星系相互作用的早期理论研究的主题。 这两个星系是由富含尘埃的潮汐桥连接在一起的。 这座潮汐桥上的灰尘在NGC 5195中心可以看到轮廓。 这表明NGC 5195似乎位于漩涡星系的后面。 这次相遇大大增强了M51的螺旋结构。 超新星1945a是一个在NGC 5195中被探测到的超新星。 1945年4月6日，米尔顿·L·胡马森 (Milton …

NGC 5195（或稱為Messier 51b、M51b）是一個和渦狀星系（M51A或NGC 5194）交互作用的矮星系。 前述兩個 星系 都距離地球約2500萬光年，位於 獵犬座 。 而這兩個星系是最著名的其中一對交互作用星系。

Some astronomers believe that the Whirlpool's arms are so prominent because of the effects of a close encounter with NGC 5195, the small, yellowish galaxy at the outermost tip of one of the Whirlpool's arms. At first glance, the compact galaxy appears to be tugging on the arm.

2013年8月31日 · Dwarfed by enormous M51 (aka NGC 5194), NGC 5195 spans about 20,000 light-years. A close encounter with M51 has likely triggered star formation and enhanced that galaxy's prominent spiral arms.

NGC 5195: NASA's Chandra Finds Supermassive Black Hole Burping Nearby One of the nearest supermassive black holes to Earth with active powerful outbursts has been discovered. Such outbursts are part of the "feedback" process that is important to the …

2024年8月9日 · 矮星系NGC 5195是螺旋星系M51的伴星系。两者在天空中刚好组成了一个宇宙级的问号，NGC 5195就是问号的点。在19世纪罗斯伯爵(Lord Rosse)手描的观测图里，它们是原始的螺旋状星云之一。

2020年7月13日 · Using multi-band photometric images of M 51 and its companion NGC 5195 from ultraviolet to optical and infrared, we investigate spatially resolved stellar population properties of this interacting system with stellar population synthesis models. The observed IRX is used to constrain dust extinction.
