Astronomers searching for signs of life beyond earth have spotted something strange. An as-yet unexplained radio signal appears to be coming from the direction is the closest to the sun – a small red star roughly 4.2 light-years away called proxima centuari.
Adding to the excitement, at least two planets orbit this star, one of which might be temperate and Rocky like Earth. What are the odds that another technological civilization would be located at the very nearest star to us?
With so many billions of stars in our galaxy? The odds seem very much against it, but all we can do is follow tha data and evidence as we learn it. The signal seemingly must either be from proxima centuari, another unrelated source within the beamwidth of the telescope, or from terrestrial interference.
Past experience suggests the third option, but there is still a lot more analysis to be done.
