From star clusters to nebul, only a century ago, the transition was thought to be easy and immediate.
It is the spectroscope that tells us so many wonderful facts about the motions of the stars, nebul and star clusters.
This rotational motion is also found in the nebul and star clusters as well as in the stars and planets.
Strewn about at infinite distances are star clusters, nebulæ, and other mysterious objects.
Star clusters in general show a similar tendency, “but to this law the globular clusters form an exception.”
It has as yet been found impossible to determine even approximately the distance of these Star Clusters.
But the chief glory of Sagittarius (and the same statement applies to Scutum Sobieskii) lies in its assemblage of star clusters.
Of star clusters about 100 are known, and such systems often contain several thousand stars.
Up from the German lines went a series of rockets and star clusters.
