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.

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 PSR J0357+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。

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.

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 R B1509 - 58已知，或简称为B1509。

X-ray pulsar being spun up, and the theory rested on titbits of circumstantial evidence.

ECONOMIST: The dizziest, giddiest stars

X-ray pulsar that spins fast enough to become a millisecond pulsar once it has consumed its accretion disc.
