Have you ever heard of SETI in the optical spectrum?

Visit the following site:


Dr. Stuart Kingsley has been searching the optical spectrum for
quite sometime and making a case for optical SETI.

Also, in the science section of the New York Times the following
appeared on 1/26/99 as pasted to the SETI mailing list by Larry

>>>Here is the text of THE NEW YORK TIMES piece (in the quickest way I
>>>can send it) from the SCIENCE section of 26 January 1999:

>>>The Search for E.T.

>>>The search for extraterrestrial intelligence, or SETI, has usually
>>>involved the ears, not the eyes. Most such projects collect and
>>>analyze radio emissions from the heavens for patterns or other signs
>>>that may indicate an alien origin.

>>>There have always been a few diehards, however, who have argued that
>>>an otherworldly civilization may be just as likely to use light waves
>>>as a means of signaling their existence to the rest of the universe.

>>>In fact, some of these proponents argue, given Earth's technological
>>>history, an advanced civilization may be more likely to use a laser,
>>>say, than a more-primitive radio transmitter.

>>>Now, the Planetary Society, a nonprofit group that has long backed the
>>>hunt for alien life, is sponsoring three new optical SETI programs.
>>>Two projects -- one at the University of California at Berkeley, the
>>>other at the Harvard-Smithsonian Center for Astrophysics -- are
>>>looking for very brief light pulses from nearby Sun-like stars.

>>>The third project, also at Berkeley, is examining data from several
>>>observatories' searches for planets outside the solar system in the
>>>hope of finding a steady, extremely narrow-frequency beam of light.

Obviously, Professor Jim Deardoff's contention that SETI only looks for
radio waves was spoken from personal ignorance of what SETI programs do
and don't do.
