位于人马座的此星云距离地球5800光年，它是一个新星团的孕育场，八百万年前新星团由云团演变而来。
Located 5, 800 light-years from Earth in the Centaurus constellation, this nebula is a stellar nursery of new star clusters born from a cloud 8 million years ago.
白矮星有时会相撞而释放出巨大能量，新星因而产生，但是每一千颗白矮星才有可能出现一颗新星，它们最终也会消失。
White dwarfs might yet be crashed together and of the mighty forces so released, new stars built, but only one star for every thousand white dwarfs destroyed, and those would come to an end, too.
现在考虑一次超新星爆发。特别是超新星1987a。
Now consider a supernova explosion. In particular, consider supernova 1987a.
这就是超新星，从地球上看原本没有星星(者是一颗很黯淡的星)地方出现了一个明亮的新星。
This is a supernova, which when seen from Earth, appears as a bright new star in a place where none (or only a very faint star) appeared to be before.
夏拉的研究兴趣包括恒星碰撞、新星与超新星，以及星团和星系内恒星的数目分布。
Shara 's research interests include stellar collisions, novae and supernovae, and the populations of stars that inhabit star clusters and galaxies.
史密斯称，几个月来这颗超新星一直以高出其他超新星的亮度照耀着。
And it has been shining at levels brighter than other supernovae for several months, Smith said.
实际上像这样的结果很重要，因为我们不知道超新星形成的黑洞和超新星形成中子星之间的分界线究竟是什么。
Results such as this might actually be important because we don't know what the dividing line is between those supernovas which form black holes, and those which form neutron stars.
俄罗斯媒体说，中国货轮“新星号”在没有得到俄罗斯准许的情况下进入俄罗斯领海，随后俄罗斯边防船只跟随“新星号”。
Russian media say border guard ships followed the Chinese vessel, the New Star, after it crossed Russia's border without its permission.
