SETI Update

Filling in for Art Bell, Ian Punnett welcomed astronomer Seth Shostak of the SETI Institute, who talked about the organization's search for intelligent life in the universe. Shostak said the United States has more SETI projects than anyone else, but several other countries have SETI programs as well, including Argentina, Australia and Italy.

Shostak also responded to Internet rumors that SETI has received an ET transmission but is withholding the information from the general public. He pointed out that there is no secrecy at SETI and it is not in the Institute's interest to suppress its findings. Despite SETI's lack of success to this point, Shostak said he expects they will find something in the next two dozen years.
