不过眼下更接近现实的是,天文学家将使用“FAST”(五百米孔径球形望远镜)来探测脉冲星 和其他天体现象。 More realistically, astronomers will use“FAST”(Five-hundred-meter Aperture Spherical Telescope) to detect pulsars and other celestial phenomena. 这次宇宙大灾难还遗留了一颗自转的中子星或脉冲星 ,这是原恒星核心的所有残骸。 The cosmic catastrophe also left behind a spinning neutron star or pulsar , all that remains of the star's dense core. 在地球一年的观测过程中,这总计使脉冲星 自转轴的方向发生了2.2度的变化。 Over the course of an Earth year of observations, this adds up to a change of 2.2 degrees in the orientation of the pulsar rotation axis. 当这些庞大的黑洞距离彼此非常近的时候,引力波波长就变得过短,无法再使用脉冲星 进行探测了。 Once these gigantic black holes get very close to each other, the gravitational waves are too short to detect using pulsars . 这次宇宙大灾难还遗留了一颗自转的中子星或脉冲星 ,这是原恒星核心的所有残骸。 The cosmic catastrophe also left behind a spinning neutron star or pulsar , all that remains of the original star's core.
这架望远镜耗资3.3亿美元建造,历时10年,科学家用来研究氢活度和脉冲星 。 Built over 10 years at a cost of $330 million, the telescope is used by scientists to study hydrogen activity and pulsars . 年1月9日,射电天文学家AleksanderWolszczan和DaleFrail宣布发现了两颗围绕脉冲星 PSR1257+12公转的行星。 On January 9, 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. 爆炸本身仅持续几秒钟,但是当脉冲星 最外层爆炸时其释放的能量令人难以置信。 The blast itself lasts just seconds, but the amount of energy released when the outermost layers of the pulsar detonate is mind-boggling.这种摇摆会导致脉冲星 辐射的到达时间与预期稍微不同。 This distortion would cause the pulsar radiation to arrive at a slightly different time than expected. 利用时间变化和脉冲星 位置,你基本上就有了超大版本的太空LIGO(真正的巨无霸)。 Using the change in time with the location of the pulsars , you basically have a giant version of LIGO in space(really giant). 这将改变脉冲星 的信号到达地球的时间,虽然极其微小。 This would change the time that the pulsar 's signals arrive on Earth, albeit very slightly. 获奖原因】“发现新一类脉冲星 ,该发现开发了研究引力的新的可能性”. Prize motivation:"for the discovery of a new type of pulsar , a discovery that has opened up new possibilities for the study of gravitation.". 唯一的纠结点在于围绕脉冲星 运行的物体是否有资格成为行星。 The only hang-up was whether the objects orbiting the pulsar should qualify as planets.这项研究提供了对脉冲星 的全面定时和X射线光谱分析,使更多的光线照射到了该天体的性质上。 The study provided a comprehensive timing and X-ray spectral analysis of the pulsar , shedding more light on the nature of this object.J0952-0607的脉冲轮廓(脉冲星 一次旋转期间的伽马射线光子的分布)显示在顶部。 The pulse profile(distribution of gamma-ray photons during one rotation of the pulsar ) of J0952-0607 is shown at the top.收件人可能会不理解,或脉冲星 的认为这是一个记录,这在一些肤浅的意义上它类似。 Perhaps the recipients will make nothing of it, or think it is a recording of a pulsar , which in some superficial sense it resembles. The time interval of two adjacent pulses emitted by the pulsar is constant.这是直接观察到脉冲星 从一种类型的天体变成另一种的证据--就像毛毛虫变成蝴蝶。 This is the first direct evidence of a pulsar changing from one kind of object into another- like a caterpillar turning into a butterfly.". 其主要工作是测量脉冲星 的大小,以更好地了解构成它的超密集物质。 Its main job is to measure the size of pulsars to better understand the ultra-dense matter that makes them up. 发现新一像样脉冲星 ,该发现出了研究引力的新的可能”. For the discovery of a new type of pulsar , a discovery that has opened up new possibilities for the study of gravitation".
