Virgo Cluster Galaxies

Explanation: Galaxies of the Virgo Cluster are scattered across this nearly 4 degree wide telescopic field of view. About 50 million light-years distant, the Virgo Cluster is the closest large galaxy cluster to our own local galaxy group. Prominent here are Virgo’s bright elliptical galaxies from the Messier catalog, M87 at bottom left, and M86 and M84 near center right. M86 and M84 are recognized as part of Markarian’s Chain, the visually striking line-up of galaxies on the that runs through the upper portion of this frame. Near the middle of the chain lies an intriguing interacting pair of galaxies, NGC 4438 and NGC 4435, known to some as Markarian’s Eyes. Still, giant elliptical galaxy M87 dominates the Virgo cluster. It’s the home of a super massive black hole, the first black hole ever imaged by planet Earth’s Event Horizon Telescope.

说明: 室女座星系团的成员星系，散布在这片将近4度宽的望远镜视野里。离我们约5,000万光年远的室女座星系团，是最邻近我们本星系群的大星系团。在这幅影像里，可以清楚见到梅西耶星表收录的数个明亮椭圆星系，包括左下方的M87，以及视野中心右方的M86和M84。其中，非常吸睛的M86和M84，是在视野右上方呈链状排列、名为马卡莱恩长链（Markarian’s Chain）的星系群之一部分。而马卡莱恩链中心附近的互扰星系对NGC 4438和NGC 4435，亦有马卡莱恩之眼的称号。不过，室女座星系团最具主宰性的成员，还是庞大的椭圆星系M87。它核心的超大质量黑洞，是地面的事件视界望远镜首张黑洞影像的主角。
