(3) The signal was so striking that its discoverer famously wrote the word “Wow!” on the margin of a printout of the data.
(4) After ruling out obvious Earthly origins, most astronomers are convinced that the signal came from somewhere beyond Earth.
(5) The question — which still remains unanswered — is where?
(6) And from what or whom?
(7) Was the signal produced by a natural phenomena?
(8) Or might it have been broadcast by some alien intelligence?
