1·The white source near the center of the image is a dense, rapidly rotating neutron star, or pulsar, all that remains of a core-collapse supernova explosion.
图片靠近中心部分的白色光源为一种密度大，急速旋转的中子星，或是脉冲星--都是核心坍缩的超新星爆炸的残留物。
2·The fast-spinning star is a pulsar, a superdense chunk of matter left over when a massive star explodes, then collapses in on itself.
这颗快速旋转的恒星是脉冲星，也就是大质量恒星爆炸后经内部坍缩形成的超高密度星体。
3·In the nebula's very center lies a pulsar: aneutron star as massive as the Sun but with only the size of a smalltown.
在星云的正中心有一个脉冲星：一个中子星，它拥有和太阳类似的质量而只有一个小村庄那么大。
4·The position of the pulsar at the upper right end of the tail is seen by mousing over the image.
脉冲星在尾巴末端右上角的位置，可以通过仔细搜寻图像查看到。
5·Three other extrasolar planets believed to be of rocky composition have been reported, but they orbit a pulsar - the flashing corpse of an exploded star - rather than a normal type of star.
之前人们曾报道过另外三颗据信由岩石组成的太阳系外行星，但是，它们是围绕着一颗脉冲星(恒星爆发后遗留的发光的残存物)运转的，而不是一颗常态的恒星。
