The Crab Nebula is what remains of the supernova of the year 1054, and inasmuch as it has been theorized that neutron stars sometimes remain following supernova explosions, it is beli ...

"A celestial cyclone, a pulsar at the heart of the Crab Nebula fires off jets of high-energy particles in this Chandra image."

在这幅由钱德拉（NASA的轨道X射线天文台）所发回的照片中，处在蟹状星云中心的一颗脉冲星正发射出一股高能量的粒子形成了天体飓风。

Now, almost a thousand years later, a super dense object -- called a neutron star -- left behind by the explosion is seen spewing out a blizzard of high-energy particles into the expanding debris field known as the Crab Nebula.

几乎是1000年后，一个超级密集的对象-被称为中子星-爆炸后的背景，也就是我们现在熟知的蟹状星云是其喷射出的高能粒子形成的区域。

Analysis shows that the accumulative excess events of steady 3TeV gamma ray emissions from Crab Nebula was increasing stably and the statistical significance reached 3.2σ, whereas no statistical significant evidence of steady 10TeV and 30TeV ga...

分析表明，来自CrabNebula的 3TeVγ射线的累积信号事例数显示了稳定增长的趋势，显著性达到了 3.2σ，但没有发现 1 0TeV和 30TeVγ射线稳定发射的迹象

Portraits of the Crab Nebula captured in visible, infrared, and x-ray wavelengths are projected on screens in Monument Valley, Utah, in a long exposure beneath a star-filled sky.

以可见光、红外线和X射线波段拍摄的蟹状星云图像被投射在犹他州的纪念谷里的屏幕上，图片是在一片布满星星的天空下使用长时间暴光拍摄的。

Analysis shows that the accumulative excess events of steady 3TeV gamma ray emissions from Crab Nebula was increasing stably and the statistical significance reached 3.2σ,whereas no statistical significant evidence of steady 10TeV and 30TeV gamma ray emissions was found.

分析表明，来自Crab Nebula的3TeVγ射线的累积信号事例数显示了稳定增长的趋势，显著性达到了3.2σ，但没有发现10TeV和30TeVγ射线稳定发射的迹象。

A pulsar is a celestial object that emits light in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.

脉冲星是一种以短爆发形式辐射光的天体。假设球型天体赤道面上有一对"发光塔"，并且这对发光塔的联线构成赤道面的直径，进一步假设光脉冲产生于球形天体的转动，那么巨蟹座星云中的一个脉冲星的闪光频率是每秒30次。
