穿过这个螺旋星系的中心是一个棒子。在这个条的中心是一个较小的螺旋。在这个螺旋的中心是一个超大质量黑洞。这一切都发生在一个巨大而美丽的棒旋星系NGC 1300中,这个星系位于大约7000万光年外的飞天河星座。这张哈勃太空望远镜合成的美丽的宇宙岛的照片是哈勃拍摄的最详细的完整星系图像之一。NGC 1300的跨度超过10万光年,哈勃望远镜的图像揭示了星系主要的中央棒状结构和雄伟的旋臂的惊人细节。巨棒是如何形成的,它是如何保持的,以及它是如何影响恒星形成的,仍然是一个活跃的研究课题。

Across the center of this spiral galaxy is a bar. And at the center of this bar is smaller spiral. And at the center of that spiral is a supermassive black hole. This all happens in the big, beautiful, barred spiral galaxy cataloged as NGC 1300, a galaxy that lies some 70 million light-years away toward the constellation of the river Eridanus. This Hubble Space Telescope composite view of the gorgeous island universe is one of the most detailed 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. How the giant bar formed, how it remains, and how it affects star formation remains an active topic of research.
