Finding repeating FRBs is even more tricky. This is because radio telescopes must be pointed at the same portion of the sky during each repeated signal. So, without knowing the timing of the repeats, it becomes even more depende...

加拿大:天文学家揭示了遥远星系发出的神秘信号的细节,这些信号由加拿大的一台望远镜捕捉到。 The precise nature and origin of the blasts of radio waves is unknown. Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion li...
A。解析:“last week”是一般过去时的时间状语,表示上周发生的事情。信号是被射电望远镜接收的,所以要用一般过去时的被动语态,结构为“was/were + 过去分词”,主语是单数,所以用was received。选项B是现在完成时的被动语态,不符合上周这一过去时间;选项C是一般现在时的被动语态,不合适;选项D是过去完成时的被动...
While the origination of the deep space radio signal remains a mystery, there is still a chance it could indicate the presence of alien life. Just last year, SETI reportedly received as many as 35 "fast radio busts" from space with the use of itsradio telescope. ...

China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has detected a repeating fast radio burst (FRB)—strange radio(signal) from outer space—for the first time. Scientists on the FAST project with the National Astronomical Observatories of China broke the newsWednesday. ...
RADIO SIGNAL TRANSMITTING FROM SPACE podcast on demand - RADIO SIGNAL TRANSMITTING FROM SPACE is an abstract memoir of thoughts, feelings and repressed memories, presented in the form of a confession that comes from the distant, deep corners of one’s se
Report: Astronomers discover radio signal from galaxy billions of light-years away Canadian astronomers have reportedly discovered a repetitive radio signal some 2.5 billion light-years away from Earth, only the second example known to mankind. A telescope in British Columbia, otherwise known as Canadi...
根据首段最后一句“Thus, for the first time, SETI is cocking its ear towards Earth to look for a signal that can be sent into space to represent the species.”( SETI首次向地球竖起耳朵,寻找可以送入太空的代表物种的信号。)可知,SETI寻找信号发送到太空是为了代表地球上的物种的声音。故选A项。【...
