Several years ago Bhathal, a researcher at the University of Western Sydney, suggested that a likely form of extraterrestrial communication would be laser bursts. He set up a facility at his lab which sweeps a nearby volume of space, within about 100 light years, for laser bursts that come in a regular pattern. Any kind of communication would likely be distinguished from background noise by coming in repeated or non-random patterns.
And a few months ago, Bhathal found the kind of regular pattern he's been looking for. He's been analyzing it and seeking a repeat pattern in the same area of space ever since. Though he's cautious about claiming it as a genuine extraterrestrial signal, his discovery has been making local news.
