An unexpected signal from a star about 94 light years away engaged the astronomers for extraterrestrial intelligence (SETI). This strong signal was received by a Russian telescope. An international team of researchers is reported to be studying the radio signal from the star HD 164595. Italian Claudio Maccone in an interview with CNN said that whenever a strong signal such as this is received, it raises a good possibility for the detection of a nearby civilisation.
Douglas Vakoch, President, METI International, which looks for life in the outer space said that the signal from HD 164595 was intriguing as it came from the vicinity of a sun-like star. He believed that the signal was strong enough to come from another civilisation much advanced than mankind. Paul Glister of the Tau Zero Foundation reciprocated Vakoch’s statement by saying that if the received signal was artificial, it had to come from a civilisation far more advanced than humankind. Such a civilisation would fit into the Type II on the Kardeshav scale. At present the Human civilisation is near Type I, where it can harness all the forms of energy available to it on its own planet. A Type II civilisation would be advanced enough to harness the energy emitted by its star completely. And achieving the feat would require a colossal undertaking, like the constructing a superstructure like a giant swarm of advanced solar panels to catch all the radiation put out by the Sun.
Though it is still difficult to understand, why a species 94 light years away would target earth with a strong signal. The star system is so far away that it could not have possibly picked up any TV or radar to inform them of human existence. Answering the doubts about the possibility of an alien life form, Douglas Vakoch pointed out that the signal could be the result of a potential technological interference among other causes. Claudio Maccone said that humans needed to learn to differentiate between these interferences and real extraterrestrial signals. Hence, the hopes of finding a more intelligent species in the outer space should not be raised very high, though such incidents are surely a step closer towards that possibility
