Astronomers have scanned the complete sky with various telescopes and detected pulsars in the milky way and nearby globular clusters .
天文学家们已经用多种望远镜扫描了整个天空,探测到了银河系内和球状星团附近的脉冲星。
Planets going round pulsars are unlikely to have life , because any living beings would have been killed , in the supernova explosion that led to the star becoming a pulsar .
When pulsars , as they became named , were discovered in the 1960s , they were nicknamed lgm for " little green men . "
当脉冲星,因为他们成为命名,在20世纪60年代发现的,他们起绰号为末次盛冰期“小绿人。”
One group is interested in mapping the distribution of hydrogen in the universe , another in the location of pulsars , and yet another is studying the structure of our galaxy , the milky way .
