The Crab Nebula -- The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 AD, is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion.

蟹状星云-蟹状星云，在公元1054结果在地球方向的编年史家所指出的超新星，是充斥着神秘的细丝，不仅极其复杂，但似乎少质量比并驱逐了原超新星从一个更高的速度比预期的自由爆炸。

The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second
