PARIS ‘Strong signal’ stirs interest in hunt for alien life
A “STRONG signal” detected by a radio telescope in Russia that is scanning the heavens for signs of extraterrestrial life has stirred interest among the scientific community.
“No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study,” said Paul Gilster, author of the Centauri Dreams website which covers peerreviewed research on deep space exploration.
The signal is from the direction of a HD164595, a star about 95 light years from Earth. The star is known to have at least one planet, and may have more.
The observation is being made public now, but was detected last year by the RATAN-600 radio telescope in Zelenchukskaya, Russia.
Experts say it is far too early to know what the signal means or where, precisely, it came from.
“But the signal is provocative enough that researchers are calling for permanent monitoring of this target,” wrote Mr Gilster.
The discovery is expected to feature in talks at the 67th International Astronautical Congress in Guadalajara, Mexico, on September 27.
“Based on the signal’s strength, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilization,” Mr Gilster wrote, referring to a scale-system that indicates a civilization far more advanced than our own.
Mr Gilster, who broke the story on August 27, said he had seen a presentation on the matter from Italian astronomer Claudio Maccone. –
