Narrator: They add some structure by burying a superthin metal armature beneath the foam.

旁白：他们通过在泡沫下方埋入一个超薄金属电枢来增加一些结构。

结果，超薄塔楼的出现并没有像脚手架上的一张纸条那样向社区发出警告。

So Fumagalli and his team used what's called the MUSE instrument at the Very Large Telescope in Chile to stare-for hours-at the edge of a superthin galaxy, until they saw that red glow.

因此弗玛加利和他的团队用智利甚大望远镜的MUSE设备观察了超薄星系边缘数个小时的时间，然后他们观测到了那种红光。
