pulsar

Most important in this case, one pulsar eclipses the other briefly every couple of hours.

更重要的是，每隔几个小时，其中的一颗脉冲星会遮挡另外一颗。

There is one other possible explanation for what scientists have seen: They could be watching the birth instead of a pulsar wind nebula.

对于科学家的最新观察结果，还有其他解释：他们所看到的或许只是一个“脉冲星风星云”的诞生。

The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand.

脉冲星是快速旋转的中子星，它向周围的太空抛射出能量，制造出复杂和有趣的结构，这个类似于太空巨手的结构便是其中之一。
