It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...

. Will Saunders of the Anglo-Australian Observatory imagines a relatively simple 16m telescope at Dome C. A nearly flat, steerable reflector (right) receives light from the sky and directs it onto the primary mirror (left). The primary mirror focuses light onto a prime-focus unit halfway between the two mirrors. This unit could be a camera, a device that holds optical fibers for capturing the light, or a secondary mirror reflecting light through the primary's central hole. Andrew McGrath, AAO
