Astrophysicist Ragbir Bhathal at the University of Western Sydney discovered a "suspicious" laser-like signal coming from the coordinates of Gliese 581 e during a SETI sweep. Bhathal is still investigating the signal and scanning the coordinates for a repeat detection.

id like to see how this one pans out. any idea how seriously SETI are taking this?
But when 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, detected the suspicious signal on a clear night last December, he knew better than to crack open the special bottle of champagne he has tucked away for the history-making occasion.
Instead, he's spent the past few months meticulously investigating whether the unrecognised signature was caused by a glitch in his instrumentation, a rogue astrophysical phenomenon, or some unknown random noise.
Even if he picks up the signal again - he's been scouring the same co-ordinates of the night sky on an almost daily basis since - the scientific rule book dictates he'll need to get it peer-reviewed before he can take his announcement to the world. "And that is a lot of ifs," he concedes.

From the moment this went on the internet or he made calls referring to this, then alphabet boys are monitoring this simultaneously. If it is something out of the ordinary then its classified as National Security and thats the end of it.
There are only two ways disclosure will come about.
1 If the governments agree to do so
2 If they land on the front lawn of the white house or some other part of the world.

Now, I understand that E is outside the habitable zone, but if I may speculate, maybe it's coming from C (which is likely to be terrestrial)...
The conditions for life could be there, but is life itself? As yet, there’s no way to know unless the planet has spawned beings that are at least as clever as we are. As part of the SETI Institute’s Project Phoenix, we twice aimed large antennas in the direction of Gliese 581, hoping to pick up a signal that would bespeak technology. The first attempt was made in 1995, using the Parkes radio telescope in Australia, and two years later additional observations were undertaken using the 140-foot antenna in Green Bank, West Virginia.
Neither search turned up a signal. But of course, the extraterrestrials might have been off the air when we were listening. Maybe their transmitter power was insufficient for our receivers, or perhaps the bandwidth we covered, from about 1,200 to 3,000 MHz, was the wrong part of the dial. There are many ways not to find an alien broadcast, but the Allen Telescope Array, now being built, will greatly improve our ability to more thoroughly scrutinize this world – and hundreds of thousands of others.

DR RAGBIR BHATHAL
Dr Ragbir Bhathal is an award winning author and
astrophysicist, who carries out research in Australian science
studies, physics and astronomy at the University of Western
Sydney Macarthur. He was the recipient of the prestigious Nancy Keesing
Fellowship in 1996, by the State Library of New South Wales. This was to carry out a major study on the scientific life and letters of Australia’s most famous 19th century astronomer, John Tebbutt. His recent book, Australian Astronomers:
Achievements at the frontiers of astronomy, published by the National Library of Australia, was on the best seller’s list. In launching the book in Canberra, the President of the Australian Academy of Science, Sir Gustav Nossal said that the publication was "an important and major book on science and astronomy in Australia".
Dr Bhathal teaches physics and astronomy and was Foundation Chairman of the SETI Australia Centre at the University of Western Sydney Macarthur. He teaches the only University based course on SETI (Searching for Extraterrestrial Intelligence) in any Australian University. Called Astronomy and Life in the Universe the course is one of the most popular courses at the University and attracts students not only from the Faculty of Science but also from the business, health, humanities and law faculties. A member of the International SETI Committee of the International Academy of Aeronautics and Astronautics and
was the Chairman of the International and Local Organising Committees of the Conference on SETI in the 21st Century. This was the first international conference in the world to discuss the scientific and social aspects of SETI. He is Chairman and Project Director of the Campbelltown Observatory at the University and is working on optical SETI with a group of scientists. He is also Foundation Chairman of the Australia-Singapore Centre and a Councilor of the University of Western Sydney Macarthur Council and is also the Foundation President of the Independent Scholars Association of Australia (NSW Chapter).
A member of the academic staff of the University of Singapore before becoming Foundation Director of the Singapore Science Centre, a "science museum of influence in the 20th century", he was a member of the senior management team that built the Power House Museum. He was the Foundation Head of the Science and Technology Division and was responsible for the supervision of the design and construction of the science and technology displays in the Museum, and was appointed as Project Director of the Sydney Observatory building restoration
and exhibit programs.
Dr Bhathal served as Director on the International Board of Directors of the Association of Science and Technology Centres in Washington, USA, and was a distinguished visitor of the US State Department. He was secretary of the Singapore National Academy of Science and the Singapore Association for the Advancement of Science of which he is a Fellow. He was Foundation President of the Singapore Society of Science Writers.
Appointed as adviser to the Australian Federal Minister for Science and was
asked to serve as an UNESCO consultant on science policy and to represent the Australian and Singapore governments at international conferences on the public understanding of science. He was the leader of the Singapore government delegation to the 6th Meeting of ASEAN Experts Group on marine pollution and has served on various high level committees of the Singapore government including the Science Council of Singapore, National R & D Committee, etc.
His publications include, Australian Astronomers: Achievements at the frontiers of astronomy; Under the Southern Cross: A brief history of astronomy in Australia; Australian Astronomer: John Tebbutt; Astronomy for the Higher School Certificate; Searching for ET; Australian Scientists and Inventors; Singapore Towards the Year 2000 (co-ed); Non-formal education in Singapore (co-ed); Singapore Science Fiction (co-ed); Government and University Research (co-ed); Cultural Heritage Vs Technological Development: Challenges to Education (co-ed)
and numerous papers in international journals..
He was former editor of the Singapore Scientist and a Contributing Editor of ASIA 2000 and has served as President of the Royal Society of New South Wales and was awarded the 1988 Royal Society Medal for services to science. Also, Dr. Bhathal was awarded the prestigious 1991 C. J. Dennis Award for excellence in natural history writing.

The "hit" found by Ragbir Bhatha was last December. It was not made with a radio telescope but by optical detection.
Please see the article I linked above regarding optical SETI.
