Explanation: Big, beautiful, barred spiral galaxy NGC 1300 lies some 70 million light-years away on the banks of the constellation Eridanus. This Hubble Space Telescope composite view of the gorgeous island universe is one of the largest Hubble images ever made of a complete galaxy. NGC 1300 spans over 100,000 light-years and the Hubble image reveals striking details of the galaxy’s dominant central bar and majestic spiral arms. In fact, on close inspection the nucleus of this classic barred spiral itself shows a remarkable region of spiral structure about 3,000 light-years across. Like other spiral galaxies, including our own Milky Way, NGC 1300 is thought to have a supermassive central black hole.

说明：庞大美丽的棒旋星系NGC 1300位在波江座之内，离我们约有7千万光年远。呈现此壮丽宇宙岛的这幅哈伯太空望远镜组合影像，是哈勃望远镜完整星系影像中最大的数幅之一。NGC 1300的跨幅超过10万光年，而这张哈勃望远镜影像，更呈现了它鲜明核心棒及壮丽螺旋臂的细微构造。在仔细检视之下，还可发现这个典型的星系之棒状核心，有个大小约为3，000光年的螺旋结构。就如同包括我们银河在内的其他螺旋星系一样，一般咸认NGC 1300也有个超大质量的核心黑洞。
