从可见光扩展到无线电波，再到X 射线和伽马射线，天文学总是会发现不寻常的物体，如射电星系、类星体和脉冲星。
The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars.
这是探测进动的关键，因为在每次遮挡期间天文学家们可以确定放射线信号的精确角度，并因此断定脉冲星的抖动时间。
That's key to detecting precession, because during each eclipse astronomers can determine the precise angle of the radio signal and therefore the pulsar's wobble over time.
鉴于脉冲星规律的射电及X射线脉冲并未发生改变，因此学者们怀疑波动源自于星云的内层。
Since the pulsar's regular radio and X-ray pulses have not altered, researchers suspect that the fluctuations originate in the inner portion of the nebula.
天文学家仍然致力于寻找太空中新的声源：黑洞碰撞，脉冲星干扰，伽马射线爆破。
Astronomers keep discovering new noisemakers in space: colliding black holes, glitching pulsars, gamma ray bursts.
这个物体，这蟹状星云的脉冲星，辐射出丰富的x射线，以及伽马射线。
And this object, this pulsar in the Crab Nebula is radiating copious amounts of x-rays, of gamma rays.
天文学家通过美国宇航局（NASA）的钱德拉（Chandra ）X射线天文台，发现了这个被称作PSRJ0357+3205（或简称为 PSR J0357）的脉冲星。 很明显，它留下了一条长而明亮的 X 射线尾巴。
Astronomers using NASA's Chandra X-ray Observatory found that this pulsar, known as PSR J0357+3205 (or PSR J0357 for short), apparently has a long, bright X-ray tail streaming away from it.
在由美国宇航局的钱德拉X射线天文台提出这个图的中心是一个非常年轻和强大的脉冲星，因为的PS RB1509 - 58已知，或简称为B1509。
At the center of this image made by NASA's Chandra X-ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short.
此外，来自脉冲星b的X射线脉冲也很强。
Besides, the X-ray pulses detected from pulsar B were too strong.
他们认为，一个已知的毫秒脉冲星与一个已知的X射线双星之间的这种相似性，为我们提示了这两类天体间长期未知的内在联系。
They suggest that these similarities between a known millisecond pulsar and a known X-ray binary provide the long-sought link between these types of objects.
射线双星就这样形成了，于是这颗中子星就向成为毫秒脉冲星迈出了关键的第二步。
An X-ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar.
射线双星就这样形成了，于是这颗中子星就向成为毫秒脉冲星迈出了关键的第二步。
An X-ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar.
