Space.com is reporting today that SETI@home will be switching its data source next year from the Arecibo Observatory in Puerto Rico, which can scan a 30-degree patch of the Northern Hemisphere Sky, to the Parkes Observatory in Australia, which can scan 70 degrees of the Southern Hemisphere Sky. Not only has the Southern Hemisphere not been surveyed nearly as extensively as the northern one, but a much larger section of our own Milky Way galaxy is visible from the Southern Hemisphere. This should greatly improve the odds of detecting an ET signal, since the odds of detecting one from another galaxy is virtually nil. More info from older articles can be found from SETI@home and from the Planetary Society. Incidentally, Sci-Fi Today has its very own SETI@home team, which you can join.
