A large number of stars bound by gravitation is generally called a star cluster or galaxy, although, broadly speaking, they are also star systems.
毕竟,星团表示许多类型星系中许多类型恒星的平均化学分布,这些星系早在太阳形成之前就已经形成了。
After all, clusters represent an average chemical distribution from many types of stars in many types of galaxies that formed long before the Sun.".
这项新研究证实,该星团拥有多个恒星群,这可能对我们对一般年轻星团的理解产生影响。
The new study confirms that the cluster hosts multiple stellar populations, which could have implications for our understanding of young clusters in general.
例如,星系可以组成巨大的结构(称为星团、超星团和灯丝),它们可以延伸数亿光年。
For example, galaxies can group into enormous structures(called clusters, superclusters, and filaments) that stretch for hundreds of millions of light-years.
梅西尔测量包括M45在内的一些星团的位置,编制成类似彗星的天体目录,在1771年发行。
Charles Messier measured the position of the cluster and included it as M45 in his catalogue of comet-like objects, published in 1771.
不过相对地用来看月表及星团时亮度会高一些,而且对暗星体的观测也有助益。
However, the relative brightness will be higher when looking at the moon and star clusters, and the observation of dark stars will also help.
The New General Catalogue of Nebulae and Clusters of Stars(NGC) is a well-known catalogue of deep sky objects in astronomy.
这个也被称为潘多拉星团的星系团Abell2744的图像是由斯皮策太空望远镜拍摄的。
This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by the Spitzer Space Telescope.
到现在为止,我们只有距离我们星系内更年轻的开放星团的距离,因为它们距离地球更近。
Until now, we only had accurate distances to the much younger open clusters inside our galaxy because they are closer to Earth.”.
通过研究星团中最亮和最热的主序星,玖富娱乐代理,天文学家估计它是在2.2亿年前形成的。
By investigating the brightest, hottest main sequence stars in the cluster, astronomers estimate that it formed roughly 220 million years ago.
一种理论认为是这些年轻的恒星通过其它较远的星团带到了这些星团的中心。
One theory is that the young stars were carried into the central cluster by other clusters that had formed farther out.
通过研究星团中最亮、最热的主序星,天文学家估计它大约形成于2.2亿年前。
By investigating the brightest, hottest main sequence stars in the cluster, astronomers estimate that it formed roughly 220 million years ago.
其中一个有助于解决这些不确定性的方法是研究年轻大质量星团,它们承载着各种大质量恒星的群体。
One of the methods that could be helpful in resolving these uncertainties is the study of young, massive clusters hosting various populations of massive stars.
新数据正在帮助天文学家了解为何该星团的恒星有不同的自转速度以及自转周期与星球组成的关联。
The new data is helping astronomers understand why stars in the cluster spin at varying rates, as well as how rotation periods relate to planet formation.
宇宙中心的引导员与您分享他们的知识,您能看到双星、星团、行星和月球。
The guides at the Cosmos Centre share their knowledge and you will observe binary stars, star clusters, planets and the Moon.
研究人员认为,这一运动,在氧气暴露时发生,有助于保护星团不受氧气的影响而完全和不可逆地散开。
According to scientists, this movement occurs upon oxygen exposure, helps to protect the cluster from completely and irreversibly falling apart in response to oxygen.
尚未编目的空间区域以程序生成的对象为特征:星系,恒星,星团,星云和行星系统。
Regions of space not yet cataloged feature procedurally generated objects: galaxies, stars, star clusters, nebulae, and planetary systems.
Bailey(1899)在星团中发现了85颗短周期变星,属于天琴座RR型变星(即星团变星);.
Bailey(1899) found 85 short-period variables in this cluster, of type RR Lyrae(or cluster variables);
七姐妹星团也被称为昴星团或M45,是最明亮和最近的疏散星团之一。
Also known as the Seven Sisters and M45, the Pleiades star cluster is one of the nearest open clusters and bright.
这个恒星组件是一个称为NGC6397的球状星团,是与地球最接近的这种星团之一。
This stellar assembly, a globular star cluster called"NGC 6397", is one of the closest such clusters to Earth.
