Explanation: Big, beautiful spiral galaxy Messier 66 lies a mere 35 million light-years away. The gorgeous island universe is about 100 thousand light-years across, similar in size to the Milky Way. This reprocessed Hubble Space Telescope close-up view spans a region about 30,000 light-years wide around the galactic core. It shows the galaxy’s disk dramatically inclined to our line-of-sight. Surrounding its bright core, the likely home of a supermassive black hole, obscuring dust lanes and young, blue star clusters sweep along spiral arms dotted with the tell-tale glow of pinksh star forming regions. Messier 66, also known as NGC 3627, is the brightest of the three galaxies in the gravitationaly interacting Leo Triplet.

说明: 庞大美丽的螺旋星系M66，距离我们只有3千5百万光年远。这个壮丽宇宙岛的跨幅约为10万光年，大小和银河系相当。而这幅经过再处理的哈伯太空望远镜特写影像，则涵盖M66核心约30,000光年的区域。在其中，可见到星系盘沿视线方向有相当大的倾角。而在它可能藏有超大质量黑洞的核心之周围，有散布着黝黑尘埃带、泛蓝星团、及发出特征粉红辉光的恒星形成区之螺旋臂。亦名为NGC 3627的M66，是重力互扰的狮子三重星系中，最明亮的成员。
