新哈勃望远镜迷上了成熟星系

这张引人注目的照片是由NASA/ESA哈勃太空望远镜的广域相机3 (WFC3)拍摄的,这是2009年安装在哈勃太空望远镜上的一个功能强大的仪器。WFC3为哈勃太空望远镜拍摄了许多许多最令人惊叹和极具标志性的照片。 如图所示,NGC 7773是一个棒旋星系的美丽例子。一个发光的棒状结构显著地穿过星系明亮的核心,延伸到NGC 7773的横扫而过的类似风车的螺旋臂的内部边界。天文学家认为,这些棒状结构出现在星系生命周期的后期,因为恒星形成物质向星系中心移动——较年轻的螺旋不像较老的螺旋那样经常具有棒状结构,这表明棒状结构是星系成熟的标志。它们也被认为是恒星的摇篮,因为它们闪耀着明亮的光芒,意味着有大
