With this distinctive central star-forming ring, and the addition of numerous bluish clusters of hot, young stars dotted through its spiral arms, NGC1097 makes a stunning visual object.

In the case of the Whirlpool Galaxy, above, you can see exactly where along its great spiral arms it's presently forming stars, just from this red glow of the hydrogen!

对于漩涡星系，如上图所示，通过氢发出的红色光，你很容易就能区分出旋臂内的恒星形成区。

The findings confirm an earlier observation by a team of astronomers, making a strong case that the Milky Way has two major spiral arms, a common structure for galaxies with bars.

此发现证实了一个天文学家小组先前获得的观察：银河系有两条主要的螺旋臂，是一个普通中心带有横条的星系结构。

The idea was revived in the1920s to explain similar irregular movements among the stars in the Milky Way and later still to describe the formation of galactic spiral arms.

在二十世纪二十年代的时候，这个观点又流行起来，用来解释银河系恒星之间类似的不规则运动。后来，该观点仍然用来解释星系旋臂的形成。

The spiral waves with mixed-mode oscillatory local dynamics are first studied using the coupling allosteric reaction-diffusion system, which gives rise to the observation of the arm-splitting phenomenon of the spiral waves. It is the first time to discover the complex sub-structure within the spiral arm.

研究了局域动力学为混合模式振荡的螺旋波动力学，发现了螺旋波的波臂分叉现象，这是第一次在螺旋波波臂内部发现复杂次级结构的存在。
