【英语时差8,16】英国天文学家,小绿人,脉冲星（下）

A little more cautious than the Soviets¹, though, the British astronomers² didn’t go public. They named the mysterious radio source LGM 1, for Little Green Men, and continued to study it. It turned out what they had was the first pulsar to be detected. A pulsar is the final state of a massive star that has collapsed³ down to about the size of New York City. As it rotates it can send out radio beams that seem, from our vantage here on Earth, to be turning on and off rapidly, like a code. But it’s an entirely⁴ natural phenomenon. Not that aliens sending out radio signals wouldn’t be a natural phenomenon as well. After all, there is one planet at least where indigenous⁵ life beams out radio signals all the time. You’re listening to one.
