M60-UCD1 is an ultracompact dwarf galaxy. It is 49 million light years from Earth, close to Messier 60 (M60, NGC 4649) in the Virgo Cluster. Half of its stellar mass is in the central sphere 160 light years in diameter. [4]

m60-ucd1是一个距离地球约5400万光年的超小型矮星系，邻近星系m60。该星系一半的质量聚集在直径160光年的中心核球中。

M60-UCD1 是距離地球4,900萬 光年，接近 室女座星系團 中的 梅西耶60 （M60， NGC 4649）的一個 超緊緻矮星系 （英语：Dwarf galaxy #ultracompact dwarf galaxy）。 它一半的恆星質量在直徑160光年的中心球體內 [4]。 藝術家概念下對M60-UCD1內超大質量黑洞的描繪 [5]。 M60-UCD1的動力學質量為 200 ± 30 million 太陽質量 （M☉） [1]，顏色和顏色梯度的缺乏表明大約 14.5 ± 0.5 billion years old （從 宇宙 年齡就可分辨的） [1][6]。 它們的 金屬量 和 太陽 相似， …

2013年9月24日 · Packed with an extraordinary number of stars, M60-UCD1 is an “ultra-compact dwarf galaxy”. It was discovered with NASA’s Hubble Space Telescope and follow-up observations were done with NASA’s Chandra X-ray Observatory and …

2014年9月17日 · Here we report adaptive optics kinematic data of the ultra-compact dwarf galaxy M60-UCD1 that show a central velocity dispersion peak exceeding 100 kilometres per second and modest rotation....

2014年9月17日 · This is a Hubble Space Telescope image of the ultracompact dwarf galaxy M60-UCD1. The galaxy crams 140 million stars within a diameter of about 300 light-years. Astronomers believe that a monster black hole resides at the center of the galaxy.

2014年9月17日 · It is inside one of the densest galaxies known to date — the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye.

The galaxy, known as M60-UCD1, is located near a massive elliptical galaxy NGC 4649, also called M60, about 54 million light-years from Earth. This composite image shows M60 and the region around it, where data from NASA's Chandra X-ray Observatory are pink and data from NASA's Hubble Space Telescope are red, green and blue.
