dwarf galaxy

a new estimate, based on its effect on the motion of a nearby dwarf galaxy, has the milky way a bit beefier than some past measurements that relied on the motions of massive stars.

基于银河系对毗连的矮星系的引力作用，研究人员作出一项新的估计：银河系比过去的测量更强大。过去的测量是以大质量恒星的运动为基础。

sn 1987a was a supernova in the outskirts of the tarantula nebula in the large magellanic cloud, a nearby dwarf galaxy.

Analysis of data later located the source of the signal coming from a dwarf galaxy three billion light years away.

通过随后的数据分析，其信号源位于一个距离地球约30亿光年的矮星系中。

Those spectacular explosions literally blow matter away, and you're left with a dwarf galaxy that's a lot like most independent films: a bit light on stars.

那些惊人的大爆炸（形成的宇宙风）将物质席卷一空，最后（星系形成的中心区域就）只剩下矮星系。这很像许多独立电影中描述的景象：夜空中闪烁着点点星光。

the researchers first used the hubble space telescope to track the dwarf galaxy leo i, which at 850000 light-years away is one of the most distant of the satellite galaxies swarming around the milky way.

研究人员首先使用哈勃太空望远镜来跟踪狮子座白矮星一号，它距离银河系85万光年，是围绕银河系运转的最远的卫星星系。

astronomers think it's a failed dwarf galaxy that lacked the requisite mass to produce stars.

天文学家们认为它是缺乏必要存在物而不能产生新星的已经衰败的矮星星系。
