室女座星系团的星系散布在这张近4度宽的望远镜视野中。室女座星系团距离我们大约5000万光年，是离我们银河系最近的大型星系团。这里最突出的是室女座明亮的椭圆星系，它们来自梅西耶星表，M87位于左下方，M86和M84位于右中附近。M86和M84被认为是马卡里安星系链的一部分，马卡里安星系链是一组视觉上引人注目的星系，贯穿了这幅图的上部。在这个星系链的中间有一对有趣的相互作用的星系，NGC 4438和NGC 4435，被一些人称为马卡里安之眼。尽管如此，巨大的椭圆星系M87仍然主宰着室女座星系团。它是一个超大质量黑洞的所在地，这是地球事件视界望远镜拍摄到的第一个黑洞。

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.
