许多螺旋星系的中心都有横条。甚至我们的银河系也被认为有一个适度的中央酒吧。在这张由哈勃太空望远镜拍摄的照片中，突出的棒旋星系NGC 1672被捕捉到了壮观的细节。可见的是黑暗的丝状尘埃带，明亮的蓝色恒星的年轻星团，发光的氢气的红色发射星云，横跨中心的明亮的长条状恒星，以及一个明亮的活动核，可能包含一个超大质量黑洞。光从跨度约75000光年的NGC 1672到达我们大约需要6000万年。NGC 1672位于海豚星座（多拉多）的方向，科学家们对它进行了研究，以找出螺旋棒如何促进星系中心区域的恒星形成。

Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1672, featured here, was captured in spectacular detail in an image taken by the orbiting Hubble Space Telescope. Visible are dark filamentary dust lanes, young clusters of bright blue stars, red emission nebulas of glowing hydrogen gas, a long bright bar of stars across the center, and a bright active nucleus that likely houses a supermassive black hole. Light takes about 60 million years to reach us from NGC 1672, which spans about 75,000 light years across. NGC 1672, which appears toward the constellation of the Dolphinfish (Dorado), has been studied to find out how a spiral bar contributes to star formation in a galaxy's central regions.
