The article talks about the frequency and strength of the signal but I didn't spot anything about its structure. What is it about this signal that is supposed

  I second this question. Unless the signal is encoding the digits of pi or something, I don't understand why it's so interesting.

  I expect that it is tantalizing for the same reason as the "Wow!" signal: "First, ["Wow!" signal] did appear to be an artificial radio signal, rather than a natural radio emission such as a pulsar or quasar. The Big Ear telescope used a receiver with 50 radio channels; the signal was only heard on one frequency, with no other noise on any of the other channels. A natural emission would cause static to appear on all of the frequencies, and this was not the case. The signal was narrow and focused, as would be expected from an artificial source." "The signal also “rose and fell” during the 72 seconds, as would be expected from something originating in space. When the radio telescope is pointed at the sky, any such signal will appear to increase in intensity as it first moves across the observational beam of the telescope, then peak when the telescope is pointed straight at it and then decrease as it moves away from the telescope. This also makes a mere computer glitch a less likely explanation, although not impossible."
