Ragbir Bhathal, an astrophysicist at the University of Western Sydney, who teaches the only university-based course on SETI (search for extraterrestrial intelligence) in Australia, has been monitoring the skys for any regular signals from space that maybe sent or emitted from an extraterrestrial intelligence.
In 2001, he suggested that maybe a laser pulse would be the signal, not the previously thought radio signal. He set out to scan the skies for regular patterns of lasers within a range of about 100 light years.
Bhathal has found the pattern that he thought he might find. He is currently continuing his testing and monitoring to be sure its not random space noise.
