Hellooo, you've got a letter from planet Mars

I read on the net that "an unexplained radio signal from deep space could -- just might be -- contact from an alien civilization."

The signal could be generated by a previously unknown astronomical phenomenon or even be a by-product from the telescope itself.

The potentially extraterrestrial signals were picked up through the SETI@home project (SETI stands for Search for Extraterrestrial Intelligence), which uses programs running as screensavers on millions of personal computers worldwide to sift through the huge amount of data picked up by the telescope.

But, as Nanoblog comments the SETI website does not mention it.

And yesterday, an article called Alien contact more likely by "mail" than radio in National Geographic News reports that a new study suggests it is more energy efficient to communicate across interstellar space by sending physical material—a sort of message in a bottle—than beams of electromagnetic radiation. Solid matter can hold more information and journey farther than radio waves, which disperse as they travel.

UPDATE:
The SETI denies the existence of any signal received from extraterrestrial intelligence.

We'll be waiting for the "mail" then!
