1967年脉冲星发现中的SETI插曲
The SETI Episode in the 1967 Discovery of Pulsars
摘要：
1967年冬天，剑桥大学的射电天文学家发现了一种新型的射电源，这种射电源看起来像是人造的，以至于几个星期以来，该小组的一些成员不得不认真考虑他们是否发现了外星智慧生物。虽然他们的调查使他们得到了一个自然的解释（他们发现了彗星），但他们讨论了如果这确实是一个人工来源的影响：如何验证这样的结论，如何宣布它，以及这样的发现是否可能是危险的。在这一点上，他们预示了SETI探测协议的许多组成部分，以及已被用来指导处理外星智慧生物探测的团体的回应的提议的回复协议。这些议定书是在大约25年后的1990年代和2000年代才制定的。利用当代和近当代的文献和后来的回忆，本文详细讨论了那个冬天发生的事情。
英文摘要：
In the winter of 1967 Cambridge radio astronomers discovered a new type of radio source of such an artificial seeming nature that for a few weeks some members of the group had to seriously consider whether they had discovered an extraterrestrial intelligence. Although their investigations lead them to a natural explanation (they had discovered pulsars), they had discussed the implications if it was indeed an artificial source: how to verify such a conclusion and how to announce it, and whether such a discovery might be dangerous. In this they presaged many of the components of the SETI Detection Protocols and the proposed Reply Protocols which have been used to guide the responses of groups dealing with the detection of an extraterrestrial intelligence. These Protocols were only established some twenty five years later in the 1990s and 2000s. Using contemporary and near-contemporary documentation and later recollections, this paper discusses in detail what happened that winter.
