Scientist declares alien signal sent from extrasolar planet!
SYDNEY, Australia - October 11, 2010 - Ragbir Bhathal, an astrophysicist at the University of Western Sydney, claims the light pulses he detected in December 2008 are from the region of space where the extrasolar planet Gliese 581g orbits a red dwarf star.
Recently, Gliese 581g was declared 100% certain to have life. Now the question has been raised, is it intelligent life?
Professor Steven Vogt of the Carnegie Institution in Washington, who declared the new-found planet to be within the elusive "habitable zone" - a zone that Vogt estimates encompasses at least 10%- 20% of all planets in the universe - stunned the world after a press conference where the he went on record stating, "Personally, given the ubiquity and propensity of life to flourish wherever it can, I would say, my own personal feeling is that the chances of life on this planet are 100%."
Since Earth's sun is a third generation star - meaning other stars developed billions of years before the sun - the prospect arises that life developed on other worlds uncounted eons before the Solar system was created. The idea is simultaneously mind-boggling and sobering.
Dr. Frank Drake, a radio astronomer who spent most of his life searching for alien intelligence with the SETI program (Search for Extra-Terrestrial Intelligence) and a past director of the giant radio telescope at Arecibo, Puerto Rico, doubted Bhathal's claim. Although Bhathal has a top reputation, Drake asserts that the Australian astrophysicist was not forthcoming with any evidence to support his claim of the signals during 2008.
Astronomers and exobiologists have argued for some time that if life is discovered on other planets within our own planetary system, it would likely be rife throughout the universe. Although some have argued that life is rare - and intelligent life rarer still - the consensus of experts has gradually turned a collective eye more favorably upon the hypothesis that life is ubiquitous and a natural evolution of the universe.
Recent findings of running water on Mars and the high presence of methane gas - strongly considered more biological than geological in origin - lend weight to the belief that Mars had life in the past and may have life presently.
Titan, the large satellite orbiting Saturn, also hints at the possibility of life.
