查尔斯·梅西耶在他18世纪的星云和星团目录中将第88个条目描述为一个没有恒星的星云。当然，华丽的M88现在被认为是一个充满恒星、气体和尘埃的螺旋星系，与我们的银河系没有什么不同。事实上，M88是室女座星系团中最明亮的星系之一，距离我们约5000万光年。M88美丽的旋臂在这幅清晰的宇宙肖像中很容易被发现。臂上排列着年轻的蓝色星团，粉红色的恒星形成区域，以及从黄色的核心延伸出来的模糊的尘埃带，这些核心主要是由年龄较大的恒星组成的。螺旋星系M88的跨度超过10万光年。

Charles Messier described the 88th entry in his 18th century catalog of Nebulae and Star Clusters as a nebula without stars. Of course the gorgeous M88 is now understood to be a spiral galaxy full of stars, gas, and dust, not unlike our own Milky Way. In fact, M88 is one of the brightest galaxies in the Virgo Galaxy Cluster some 50 million light-years away. M88's beautiful spiral arms are easy to trace in this sharp cosmic portait. The arms are lined with young blue star clusters, pink star-forming regions, and obscuring dust lanes extending from a yellowish core dominated by an older population of stars. Spiral galaxy M88 spans over 100,000 light-years.
