SETI : Alien signal detected?

The Guardian is reporting that the SETI at Home project may have detected an alien signal originating in the constellations of Pisces and Aries. The signal has been observed three times in the past year. The Telegraph , New Scientist and The Scotsman are also reporting on it.

"This radio signal, now seen on three separate occasions, is an enigma. It could be generated by a previously unknown astronomical phenomenon. Or it could be something much more mundane, maybe an artefact of the telescope itself.

But it also happens to be the best candidate yet for a contact by intelligent aliens in the nearly six-year history of the SETI@home project, which uses programs running as screensavers on millions of personal computers worldwide to sift through signals picked up by the Arecibo telescope."
