The ring of stars saps the momentum of incoming gas, so it spirals in towards the black hole.
有着与众不同的中心恒星环，旋臂上还点缀着大量炽热的年轻恒星组成的蓝巨星簇，NGC 1097就成为绝佳的观测目标。
With this distinctive central star-forming ring, and the addition of numerous bluish clusters of hot, young stars dotted through its spiral arms, NGC 1097 makes a stunning visual object.
