1.(Astronomy) any of a vast number of star systems held together by gravitational attraction in an asymmetric shape (anirregular galaxy) or, more usually, in a symmetrical shape (aregular galaxy), which is either a spiral or an ellipse. Former names:island universeorextragalactic nebula ...
A spectrum taken of one of the probable cluster members shows a tentative likeness to that of a K3 III-star (with an age of at least 20 Myr). If correct, this would confirm the kinematic distance. Conclusions. This cluster is the furthest one from the Galactic center yet detected. The...
At the same time, the discovery of this star will allow astronomers to gain new insights into the galaxy cluster itself. As Steven Rodney indicated, “We know that the microlensing was caused by either a star, a neutron star, or a stellar-mass black hole.” As such, the discovery of ...
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 ...

What if we view a cluster, agalaxyor the moon? 如果我们看的是星簇, 星系或者月亮 怎么办 ? 期刊摘选 Is NGC 7582 a StarburstGalaxy? NGC7582是一个星爆星系 吗 ? 期刊摘选 Eachgalaxycontains myriads of stars. 每一星系都有无数的恒星.
the centre of theglobular clustersystem—a huge almost spherical cloud of clusters—lies in that direction, some 30,000 light-years from the Sun. Shapley assumed that this centre must also be the centre of the Milky Way Galaxy. The globular clusters, he argued, form a giant skeleton around...
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...
As a result of Baade’s pioneering work on other galaxies in theLocal Group(the cluster ofstarsystems to which the Milky Way Galaxy belongs), astronomers immediately applied the notion of two stellar populations to the Galaxy. It is possible to segregate various components of the Galaxy into th...
