A simplified dendrogram of these structures is shown on the bottom, with names of known galaxy clusters labeled above the nodes. 3.1.3 Star cluster Stars may also assemble into clusters like galaxies. There are two types of star clusters: globular clusters and open clusters. The former are ...
Observations of a distant cluster of galaxies suggest that star formation began there only 370 million years after the Big Bang. The results provide key details about where and when the first stars and galaxies emerged in the Universe.
Another image below I was battling with a bit of light pollution. But prominently you can see Jupiter and towards the top are the Pleiades Star Cluster and at the bottom is a line of stars that make Orion's sword In full resolution on my phone, the images look amazing. Sadly...
集群(Cluster):共用同一ResMan的host/agent及服务 机器池(Pool): 一个host/agent只能属于一个机器池,一个机器池通常有很多host/agent。一个集群中可能有多个机器池。机器池用于资源及环境的硬隔离, 也是权限分配的单位。 用户(User):galaxy用户 权限(Authority):某用户在某机器池上具有的某种操作权限,如对Job的增...
Satellite galaxies in groups and clusters aremore likely to have low star formation rates (SFRs) and lie on the 'red sequence' than central ('field') galaxies. Using galaxy group/cluster catalogues from the Sloan Digital Sky Survey Data Release 7, together with a high-resolution, cosmological...

It is therefore not likely that the object is a background galaxy. Assuming the object is a star cluster in the disc of M 51, we estimate an age and mass of Gyr and , respectively (with the extinction fixed to ). Considering the large size of the object, we argue that in ...
Many of them are more akin to the size of a star cluster at their largest. However, in Super Mario Galaxy 2, a galaxy proportionate to a real galaxy appears in the background of World 4, while in World 5, there is a galaxy supercluster. There are solar systems that can be seen ...
