Sydney, Australia - Instead of listening to possible alien radio signals, Australian OSETI-Astronomers looking for possible intelligent laser pulses from distant civilizations have detected an unknown signal that could not have been identified yet.
Contrary to the classical Search for Extraterrestrial Intelligence, (SETI) that is listening to intelligent radio signals from outer space, so called "OSETI" is searching for strong "optical" laser pulses or strong laser flashes. While SETI-researchers dismiss the idea of crop circles being a communication from aliens because - according to Seth Shostak of the SETI Institute - alien visitors with the ability to travel to Earth would surely use a more sophisticated technology to communicate, such as radio transmission, the idea of OSETI turns this argument around (even if certainly not in favour to the much debated crop circle phenomenon): "For an advanced civilization, radio wave technology would be old hat. (...) My strong feeling is that if there are (extraterrestrial intelligence) civilizations out there, they will send the signal by laser pulses or laser flashes", explained Dr. Ragbir Bhathal head of the "OZ OSETI PROJECT" at the University of Western Sydney in an interview with "The Australian"...
