这是恒星爆炸后留下的混乱景象。蟹状星云是公元1054年一颗超新星的产物，它充满了神秘的细丝。这些细丝不仅极其复杂，而且似乎比最初的超新星释放出的质量要小，而且速度比自由爆炸预期的要快。这张由哈勃太空望远镜拍摄的特色图片以三种颜色呈现，以供科学研究参考。蟹状星云的跨度约为10光年。在星云的正中心有一颗脉冲星：一颗和太阳一样大但只有一个小镇大小的中子星。蟹状星云脉冲星每秒大约旋转30次。探索+拓展：APOD研究生研究职位开放

This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments 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. The featured image, taken by the Hubble Space Telescope, is presented in three colors chosen for scientific interest. 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.
