原文:
The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy. The Virgo Cluster is so close that it spans more than 5 degrees on the sky – about 10 times the angle made by a full Moon. With its heart lying about 70 million light years distant, the Virgo Cluster is the nearest cluster of galaxies, contains over 2,000 galaxies, and has a noticeable gravitational pull on the galaxies of the Local Group of Galaxies surrounding our Milky Way Galaxy. The cluster contains not only galaxies filled with stars but also gas so hot it glows in X-rays. Motions of galaxies in and around clusters indicate that they contain more dark matter than any visible matter we can see. Pictured above, the heart of the Virgo Cluster includes bright Messier galaxies such as Markarian’s Eyes on the upper left, M86 just to the upper right of center, M84 on the far right, as well as spiral galaxy NGC 4388 at the bottom right.

🚀✨ **維爾戈星系團**（Virgo Cluster of Galaxies）是距離我們**銀河系**（Milky Way Galaxy）最近的星系團。由於它的距離很近，維爾戈星系團在天空中佔據超過5度的範圍——大約是滿月角度的10倍。該星系團的核心位於約7000萬光年外，擁有超過2000個星系，並對我們銀河系周圍的**地方星系群**（Local Group of Galaxies）產生明顯的引力影響。這個星系團不僅包含充滿恆星的星系，還擁有發出X射線的高溫氣體。星系在星系團內外的運動顯示，這些星系團中包含比我們所能看到的更多暗物質。
在上述圖片中，維爾戈星系團的心臟部分包括許多明亮的梅西耶星系，例如上左方的**Markarian’s Eyes**，中心偏右的**M86**，右側的**M84**，以及右下角的螺旋星系**NGC 4388**。
