“We were doing the normal run on our 0.4 meter (16 in.) Telescope in December 2008 and found this spike on our computer screen,” said astrophysicist Ragbir Bhathal, Director of the Australian Optical SETI Project at the University of Western Sydney Campbelltown. “It was quite exciting to see this very sharp signal and I wrote on the print-out “Is it E.T.?” But alas, No. Although Bhathal said there was no fault with the instruments; six months of trying to relocate the signal turned up nothing. “We have now dismissed it as spurious,” said Bhathal, who notes that instead of an intelligent signal from E.T., the spike was most likely caused by wayward cosmic rays.
The signal Bhatal detected also did not come from Gleise 581. Not from anywhere near the Gliese system. It came from 47 Tucanae, about half way across the sky from Gliese.
About the signal, it seems that Dr Ragbir Bhatal thinks it was most likely caused by wayward cosmic rays.
In December 2008 a sharp laser look alike signal emanating from 47 Tucanae was detected. However, further searches in the same region have failed to detect the signal again.
That's interesting because some posters cited recent claims that the signal didn't come from Gleise.

I don't know about anybody else, but I think we have found the first location outside of our solar system that we should visit.
How long would it take us to travel 20LY with today's tech?edit on 10-1-2013 by watchitburn because: stupid autocorrect.

Nice idea but the math doesn't work.
A signal from earth at the speed of light would take 20yrs to to travel 20 light years.
Then whatever they send back would take 20 years to get hear. Add time for political bickering.
At the minimum their return message would not arrive until 2014. That is probably a low estimate as wikipedia estimates gilese 581 to be 22 light years from earth. By that estimate it would take a return signal until 2018 to reach Earth, assuming it was replied to immediately.
... unless you assume they can somehow exceed light speed.
Dr Bhathal had been sweeping the skies when he discovered a 'suspicious' signal from an area of the galaxy that holds the newly-discovered Gliese 581g.
The remarkable coincidence adds another layer of mystery to the announcement last night that scientists had discovered another planet in the system: Gliese 581g - the most Earth-like planet ever found.
Dr Bhathal's discovery had come just months before astronomers announced that they had found a similar, slightly less habitable planet around the same star 20 light years away. This planet was called Gliese 581e.

I think we will eventually find it to be 'the norm' for some planets with life on to maybe have 2 or 3 other planets in the same solar system with life. Imagine that if there was a completely different intelligent species living on mars
