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。这张特色图片是由美国佛罗里达州利斯堡的一位业余天文学家在上个月的三个晚上拍摄的。它以三种原色被捕捉到，但由于氢气的特殊发射，它提供了额外的细节。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。探索宇宙：随机APOD生成器

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 was taken by an amateur astronomer in Leesburg, Florida, USA over three nights last month. It was captured in three primary colors but with extra detail provided by specific emission by hydrogen gas. 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.
