所以当一个巨大的恒星自我爆炸，它将继续一直爆炸，直至到达无限密度的一个点。
So when a massive star collapses in on itself, it will keep and keep collapsing until it gets to a point of infinite density.
MyCn18之所以呈现出沙漏的外形，是因为一个缓慢扩张的云团里迅速向外冲去的恒星风造成的，其“赤道”附近的云团密度要大于两极。
MyCn18's hourglass shape is thought to have arisen from the expansion of a fast stellar wind within a slowly expanding cloud which is denser near its equator than its poles.
与太阳不同，太阳密度太高，能够支持生成强烈太阳光的核聚变，而Gliese 581是颗红矮星，之所以这么叫是因为这个恒星又小又暗。
Unlike the sun, whose density is such that it supports nuclear fusion that generates bright sunlight, Gliese 581 is a red dwarf, so-called because the star is small and dim.
白矮星是一种高热度、高密度的晚期恒星。
White dwarfs are the hot, superdense remnants of spent stars.
原指光度大、体积大、密度小的恒星；本文比喻某些方面有杰出成就的伟人。
Originally, superstar refers to stars in big luminosity, big volume and low density. It is a metaphor of some people with outstanding achievements in some aspects.
引力会使密度波穿透星系，继而形成炽热、耀眼的年轻恒星，产生我们在图片中看到的光环。
Gravity, however, causes density waves to move out through the galaxy which in turn triggers the formation of hot, bright young stars, producing the ring that we see in this picture.
这颗恒星的密度如此之大，以至于它会在某一时刻爆炸。
The density of the star has become so great that it may explode at some time.
当大质量的恒星耗尽了核能源、坍塌并被压缩到一个紧密和密度达到连光线也逃脱不了它们的引力的时候，黑洞便产生了。
Black holes form when massive stars run out of nuclear fuel, collapse and become so compressed and dense that not even light can escape their gravitational pull.
